How Do I Know What Air Filter To Buy?

Pleated filter? Fiberglass filter? Electrostatic filter? Which one is for me?


Pop quiz. What is the best way to rid your indoor air of pollutants like mold, pollen, and bacteria?

  1. Napalm your entire home
  2. Walk around the house waving a disinfecting wipe through the air
  3. Vacuum the air with a shop vac
  4. Purchase the right air filter

If you chose D, you are correct. If you chose any other option, then we need to have a separate conversation.

An air filter plays a critical role in keeping the air in your home clean. In fact, it’s the most important item to your home’s air that you can purchase, and since your indoor air can be up to five times more polluted than the air outside (and no one likes breathing pollutants), you need a high-quality air filter.

There are a lot of different varieties of air filters that you can purchase. Given that the average person ranks air filters right around different types of cement and how cardboard is made on the list of things that interest them, it’s not surprising that many don’t know what makes a quality air filter “quality.”

Luckily, all you have to do is read this one article, and you’ll have the answer to that question. Then all you have to do is sign up for Second Nature once, and you’ll never have to think about some air filters ever again.

What type of air filter should I get?

Filters can only be made so many ways. For home filters, you have three options. You can buy a pleated filter, you can buy a fiberglass filter, or you can buy a washable reusable filter. Each type has its disadvantages, and two of them have their advantages, so let’s take a closer look at what those are.


Pleated filters get their name from their filter media, which is the material inside the frame that is responsible for the actual filtering. A pleated filter’s media is folded like an accordion to maximize surface area. Previously made of cotton, the pleated filters of today are built with synthetic polymers that allow for effective filtering while minimizing the impact on airflow.

The advantages of pleated filters include their high filtering efficiency. High MERV filters are almost always of the pleated variety. The pleated filters work to capture an extremely high percentage of large particles and a much higher number of small particles than competing filter types.

Pleated filters are low effort and high functionality. The only thing you ever have to do is remember to change them out, and they’ll keep pulling gunk out of your air.


Fiberglass air filters are the cheapest on the market, sometimes costing less than a single dollar. There is a reason they are so cheap, and it is because they are garbage. Yes, fiberglass filters are garbage. Fiberglass filters are the weakest option and are recommended by the National Air Filtration Association only as “prefiltering” devices because of how ineffective they are. Simply put, they are bad at their job.

There’s a myth that fiberglass filters are better for your HVAC system because they allow for more airflow. While they do allow for that, advancements in HVAC and filter technology have made the difference immaterial. The extensive amount of pollutants they allow to flow through can actually make them more dangerous to your system than the pleated variety.

The reason why fiberglass is often recommended is that people don’t remember to change their filter. As a pleated filter loads with pollutants, it can eventually decrease airflow to a critically low amount. Fiberglass doesn’t do this because of how woefully ineffective it is at actually catching particles. So as long as you’re regularly changing your filters, there is not a single advantage to the fiberglass option.

Washable Electrostatic

Washable electrostatic filters are metal-frame filters that are designed to be washed and reused instead of replaced. The price range for these is wide, with the most expensive ones entering the $90 range.

The advantage with these filters is their longevity. While they do eventually wear out, they can be reused for multiple years before that happens. The disadvantage is that you do need to wash them routinely and let them dry completely before reinserting. This can eat into your busy schedule as they don’t dry instantly, and if your washable filter doesn’t fully dry, mold growth can be a real issue.

Washable filters also do a poor job collecting large particles. Because static electricity is really the only filtering mechanism they use, they struggle to attract the larger particles that are more difficult to pull with a charge. Thus, washable filters tend to work in reverse of fiberglass as they let larger particles through and filter out smaller ones.

What quality of filter should I get?

After you know what type of filter is right for you, you need to know what rating is right for you. Filters can be rated on three separate scales. The scale used by us at Second Nature and the official folks at the National Air Filtration Association is the MERV scale, which stands for minimum efficiency reporting value.

The MERV scale runs from 1-16. Second Nature offers filters rated at MERV 8, MERV 11, and MERV 13, which are our Essential, Essential+, and Health Shield, respectively. Anything below an 8 is something that probably shouldn’t be in your home. Anything above a 13 is not necessary except for maybe in an extreme case, which is why we offer the range we do.

Other filter scales include FPR and MPR, which stand for Filter Performance Rating and Microparticle Performance Rating. FPR was a scale developed by The Home Depot for the brands that it sells. The scale ranges from 4-10 and includes a color code for each range. MPR was developed by 3M and, it ranges from 300 to 2800. The scale is based on the filter’s ability to capture particles under 1 micron in diameter and is only found on 3M Filtrete filters.

Here we have provided a conversion chart with MERV vs. FPR vs. MPR so you can understand what you’re getting if you decide to purchase from somewhere that rates their filters with one of those less popular scales.

merv, fpr, and mpr comparison chart

Deciding on what MERV rating is right for your home is a decision that must be made based on a handful of personal factors.

Are you an allergy sufferer?

More than 50 million Americans have some type of allergy. Allergies are everywhere, and if you’re among the millions of Americans who suffer from them, your filter can help you keep those nasty allergens out of your home.

The severity of your allergies will help determine just how critical filtration is for your home. If you have a significant allergy to something that is prominent in your area, you’re going to want to increase your indoor air quality with a Second Nature Health Shield filter (MERV 13) or equivalent level. More minor allergies or allergies to something that doesn’t exist in massive quantities around your home may allow for a drop down to a Essential+ filter (MERV 11).

Do you own pets?

Owning a dog or a cat introduces a whole new threat to your indoor air quality: dander. Dander is small flakes or bits of skin that fall off your furry friend when they shed, and some people are violently allergic to it.

If you are among that group, a Health Shield air filter is a must. Pet dander is small, and a MERV 8 filter is likely not sufficient for you allergy sufferers out there, and that fiberglass nonsense certainly is not. Essential+ and Health Shield will both be effective versus pet dander. If you’re allergic, get the MERV 13 Health Shield. If you’re not allergic, but you own pets, the Essential+ will work well for you.

Do you live in a polluted area?

Air outside your home will become air inside your home. It is inevitable. No matter how much weatherstripping you install or how well-sealed your home is, there will be particles floating around outside that will get inside. This is particularly important to remember if you live in areas that see a lot of air pollution from things like smog. Those of you in California, as you certainly know already, can get hit pretty heavily with photochemical smog in the summer. The state is often also hit with smoke pollution during wildfire season, which also runs through the summer and fall.

The particles that make up smoke are itty-bitty, smaller than a tenth of a micron. For perspective, you would need at least 3,000,000 of those particles lined end to end to equal one foot. If you frequently encounter smoke or smog around your home, a Health Shield (MERV 13) is recommended.

Still not sure what filter to get? Take our short quiz!

  1. Do you have allergies to pollen, dust, mold, or dust mites?

A. Yes, severe allergies (add 2)

  1. Yes, mild allergies (add 1)
  2. No (add 0)
  3. Do you own a dog or cat?
  4. Yes (add 1)
  5. No (add 0)
  6. Are you allergic to pet dander?
  7. Yes (add 1 if answer to #2 is A, 0 if B)
  8. No (Add 0)
  9. Do you live in a polluted area?
  10. Yes, very polluted (Add 2)
  11. Yes, slightly polluted and no smoke or smog pollution (Add 1)
  12. No (Add 0)


What size air filter should I get?

As the saying goes, there are three things you can’t pick: your parents, your name, and your filter size. That’s a real saying that we did not just make up eight seconds ago.

Simply, you need the filter size that fits in your air return. You can typically find that size on the side of the air filter that you already have in use. This size will be the nominal size, which means it is rounded from its actual size. This is the size you click on at

If you don’t have a reference point from an old filter, you’ll need to use a tape measure and measure your vent. These measurements will be the exact size, and you’ll need to add ¼” to both length and width to get the nominal size.

If you have a filter that is four inches thick or thicker, you have a whole house filter. There is no rhyme or reason to how these filter sizes are rounded. Luckily, all you’ll need at is the actual size of the filter.

Buying an air filter isn’t always easy, and knowing what air filter to buy is the hardest part. However, if you have read this far, you’re good. So congratulations! Here’s an air filter gold star. You can print it out and tape it to your shirt if you want. You’ll probably get a lot of strange looks, but that’s not your problem.

How to Optimize Operational Frequency with Processes and Software

Property management software is currently helping property managers establish efficient and reliable processes at a higher rate than ever before in the PM industry. With that development in the proptech industry has come the development of tech for self-managers that has changed the capacity of the accidental landlord. Thus, the demand for efficiency at scale has risen in order to separate the professional from the amateur, and the establishment of processes that allow such a thing has become a critical topic for professional property managers. Optimizing property management processes Carter Fleck of Triton Property Management, a growth-oriented firm out of northern Virginia that is approaching 300 units with larger goals for 2024, joins us to share his expertise on process definition. Fleck is the General Manager responsible for operations and strategic growth, and he has been developing effective processes to ensure efficiency at Scale at Triton, and in the process, he has garnered an understanding of how to do so. “A lot of failing,” says Fleck. “In the early days, we were getting a lot of good and bad feedback, but typically the bad feedback is what you adjust off of.” Fleck believes that assumptions are the enemy when it comes to defining procedures and sourcing software for your PMC. “The image that we use is if you're going to build a sidewalk before people even start walking on a field, it's kind of dumb. You have to see where people will walk first, and then you'll build a gravel path. So number one, you see where they walk, see where their intentions are in the grass, then you build a gravel path. And then eventually, once that walkway is established, that's where you build your processes and procedures.” The analogy is a visualization of the concept that you have to see how people operate before you can establish processes to make how they operate more efficient. Fleck encourages the negative experiences of process breakdown and cites them as the only way to really nail down what your processes should look like. “Over time, between the tenants giving feedback and owners giving feedback, we adjusted our processes. It's a mix between figuring out where the owners walk and where the tenants walk, and then building paths that align.” Fleck details an example of how Triton adjusted its process after an assumption it made got challenged: "We had an assumption that payment plans were helpful for residents," says Fleck. "And so the way we handled delinquency is we would reach out to them and would be like, ‘you need to pay this. Do you have a payment plan option?’ And they would always say yes. Our process was we'll put you on a payment plan, we'll invite you to a payment plan, you'll accept the payment plan, and then we'll monitor the payment plan. That in itself was a lot of work, but we thought it was doing well. But some of the owners that we had managed for mentioned that another property manager doesn't allow any payment plans. And if you're not fully paid up by the end of the month, then the eviction process starts if you’re over $500 due. So we're like 'alright, well, we'll serve you in that we'll change our processes.' And we did, and our delinquency percentage shrunk significantly. So, consistently, by the end of every month, we're around 5% APR. Whereas with payment plans we're like 5 to 10%.” Fleck obviously credits seeing the assumptions in motion as what prompted the need for process iteration, and he firmly believes that making too many of these assumptions is one of the biggest mistakes growing property management companies make. Like any business experiencing growth, process definition is critical to achieve efficiency at larger volumes. What Fleck is essentially advocating for is processes based on what you know, not what you think, and there is a big distinction. Managing property management software Fleck has installed both general and tech-based processes, and cites that understanding of how people interact with processes as the key in both areas. "They don't focus on user experience. That's really important. Number one, how the tenants like the tech, but specifically how the people who are using the tech are gonna adopt it. So when we were choosing a rent inspection software, we had so many people recommend one, software and I, we almost pulled the trigger on it. But then I was like, let's do a trial run on both these two. And we chose the other one because it was way better user experience for property managers. So user experience, both for us and for residents." Tech is a tool that is ultimately as good as its users, and if it's not used correctly or at all, its potential is wasted. An over-reliance on technology can actually go hand-in-hand with an under-reliance, as both often spring up from a lack of understanding of how to choose, implement, and manage it. In this vein, Fleck can't recall many property managers who operate with too much tech. As long as you're not purchasing redundant software and you've done and continue to do your due diligence, tech-based process can make your business more efficient. "I more often find myself having that conversation," says Fleck. "When I'm talking to property managers in my sub-market, who aren't connected with like a NARPM, who aren't connected with like a Crane group, or who aren't connected with a Second Nature, aren't connected to the tune of what the property management industry is doing and the cutting edge of it, I'm just like, 'you could save so much of your time and you could scale this so much more if you only even if you just had tenant Turner, or if you had LeadSimple.'" No matter what your story is a property manager, if growth is in the cards, so is process and technology refinement. Hopefully, Fleck's experience in these areas can help you stay efficient and organized as door counts grow.

Why offer a tenant benefits package?

In the residential real estate sector, like everywhere else, residents and property investors alike are getting younger – and with this generational shift comes expectations for a certain level of convenience and support. To put it bluntly, today’s residents want their needs proactively anticipated. It’s something they're willing to pay (and stay) for. That’s where a tenant benefits package comes in. In this article, we’ll explore what a tenant benefit package is, how it improves the experience for both property managers and tenants, and crucial mistakes to avoid. Before we get into the details, we want to give a shoutout to our very own “Resident Benefits Package” – which is how we refer to the benefits comprised in the “tenant benefits package.” “Tenant” is not yet a legacy term, but we here at Second Nature are trying to evolve it. That’s because, in our experience, property managers work hard to make renters feel like they’re not just parties to a contract – they’re residents. On one hand, this is just humans being humans, but on the other hand, it also encourages them to invest in care for their new home and add value to the property. Ready to get started now? Build your Resident Benefits Package today. What is a tenant benefits package? A tenant benefits package is typically a bundle of services, conveniences, and provisions offered by a property manager on top of the basic lease agreement. They represent a triple-win situation for property managers, residents, and property owners, as they enhance the overall rental experience, generate additional income, and protect the real estate investment. It might include conveniences such as online monthly rent payment options, or portals for submitting maintenance requests and tracking their status. It could also include various financial perks, such as credit rating improvements that are contingent on on-time rental payments, or discounts on nearby services such as fitness centers. It might also include amenities ranging from move-in concierge or utility set-up services, to identity protection services, to HVAC filter delivery. The cost for resident benefits packages is typically included in the lease and added as a monthly fee, with the fee being dependent on the specific benefits. Indeed, the benefits contained in a tenant benefits package will vary depending on the property manager and the type of rental property. The overall goal is to provide tenants with an enhanced quality of life while simplifying the experience of renting. At Second Nature, we pioneered the only fully managed resident benefits package, in response to PMs who wanted to make their business stand out. Our RBP includes an array of services and supports for residents, from filter delivery to credit building to maintenance. Why should property managers offer a tenant benefits package? Beyond the triple-win considerations mentioned just above, there are compelling and concrete reasons why property managers should offer tenant benefit packages. We'll turn to these now. Ancillary revenue Some tenant benefit packages include optional services or add-ons that can generate additional revenue streams for the property manager. This might include things like renter insurance or HVAC filter delivery. Resident experience Tenant benefit packages deliver numerous savings and value to tenants, beyond the value they would get if they were obtaining the same benefits "à la carte." Additionally, by offering additional services and conveniences, benefit packages can make tenants feel valued and more satisfied with their living experience. For instance, maintenance hotline requests, tenant portals, and air filter replacements all make life easier. Add-on services like identity theft protection can offer a sense of security. And discounted renters insurance coverage, utility concierge services, or other perks can save tenants money. Decrease tenant turnover and vacancy rates In a competitive rental market, tenant benefit packages can be a major differentiator toward boosting retention rates and reducing vacancy rates. Properties that offer these packages can also attract a wider pool of qualified tenants, and potentially command higher rents. Note that certain benefits in the package, like online rent payments and maintenance requests, can automate tasks and free up the property manager's time. This allows them to focus on more value-added initiatives. How does the tenant benefits package improve the tenant experience? Tenant benefit packages can significantly improve tenant satisfaction in several ways, by making life easier, more convenient, and potentially more affordable. For instance, if an online portal (a baseline feature for most property management software) is included for rent payments and maintenance issues and requests, this eliminates the hassle of writing checks or waiting on hold to speak with someone about a clogged drain. In other words, tenants have the peace of mind of knowing they can manage their tenancy 24/7 from the comfort of their own devices. Some packages might include features like filter delivery services or regularly scheduled HVAC maintenance. This frees tenants from having to remember these tasks – and ensures their apartment is well-maintained. Certain packages might also offer "verified vendor" services – in other words, a vetted vendor network that can help provide a more secure feeling to residents when service providers are on-site. On the financial side of things, a benefits package might offer discounts with local suppliers for various goods and services, or on a renters insurance policy obtained through the property manager (with applicable waivers for residents who have their own insurance). This can save tenants money on a necessary expense. Some packages also help residents with their credit scores via credit reporting and credit building services, so they can transition from renting to home buying when the time is right. The idea is that the credit reporting program reports on-time rent payments automatically to all credit bureaus, helping residents build their credit simply by paying their rent on time. Some benefit packages include resident rewards programs that represent a powerful and positive incentive for on-time rent payments, including gift cards or cash. As far as living perks go, packages sometimes include added benefits such as access to fitness centers or community events. This provides tenants with additional spaces to relax, socialize, or stay healthy. Packages can include security deposit alternatives that serve to provide a means for residents to be financially liable for damages without having to pay a significant lump sum upfront, such as pure insurance, surety bonds, and ACH authorization programs. Ultimately, tenant benefit packages create a more professional and responsive image for the property management company, which helps tenants feel valued and allows them to experience a smoother, more stress-free rental experience. What are the mistakes to avoid when offering tenant benefits packages? Property management companies should take care to avoid certain pitfalls when implementing tenant benefit packages to ensure they are providing true value to tenants as well as delivering profitability to the PM company itself. For instance, it's important to ensure that the services you're offering are actually relevant to your target renters. For example, young professionals might appreciate discounts on gym memberships, while families might prefer pet-sitting services. You should also take care to clearly communicate what's included and not included in the package to new residents. Don't oversell the benefits – focus on how they genuinely improve the living experience. It's also very important to set realistic expectations for response times on standard maintenance requests, emergency maintenance requests, or virtual concierge services. Likewise, be clear on all available payment methods, as well as rent due dates, late fee structures, and any associated payment processing fees. If your package includes services from third-party vendors, ensure that these vendors are reputable and reliable. Research their customer service record and responsiveness to ensure a smooth partnership and a positive experience for tenants. Above all, regularly monitor the usage of different benefits within your benefits package. This can help you refine your offerings and ensure you're not spending where spending is not required. Looking for a Resident Benefits Package? If you’re looking for a “plug and play” resident benefits package, Second Nature’s RBP is the way to go. Designed to be easy to implement and simple to use, all the services it includes are managed by Second Nature – which means there’s no day-to-day upkeep required from the property manager: Second Nature keeps it running.
