I Tried Second Nature Air Filters. Here’s My Review (2025)

Second Nature Air Filters Review

It’s that beautiful time of year when the weather warms and the trees and flowers start to bloom. While we’re all happy for more sun and fun outside, the beginning of spring can cause many of us to get itchy water eyes, runny, stuffed up noses and start sneezing and wheezing like maniacs. Yup – it’s spring allergy season.

While allergies can sure be a nuisance this time of year, spring time isn’t the only reason allergies can kick up. In fact, the air inside our home can be a major allergy trigger, circulating with allergens like dirt, dust, pollutants, pet dander and mold spores that can affect us year round. So what do we do? While keeping up on your vacuuming can help, the easiest way to minimize exposure to these allergy inducing air invaders is to… drumroll please – change your air filter or filters. If you were expecting something more glamorous, we apologize. But this one quick and easy home care step can make a huge difference in the quality in the air in your home. Air filters work to trap allergens to keep them from circulating through your home. And when the air in your home is healthy, so are the people and pets living there.

The thing with changing the air filter in your home is, it’s almost too easy. Like, most of us forget to do it easy.

Maybe you didn’t even realize you were supposed to do it at all. And if you’ve just moved into a home or apartment that isn’t brand new, there’s no telling when the air filter was changed, if ever. Ew. That’s okay, because we’re here to help.

The best way to stay on top of this one super important task is with Second Nature (formerly FilterEasy). Second Nature is a home air filter subscription service that delivers air filters to your home exactly when you need to change them. It’s so simple, it’s genius!

Here’s why Second Nature and clean home filters are a must have for your home:

Keeping The Air Clean In Your Home Is Important For Staying Healthy And Keeping Allergies At Bay

When the air filters in your home are old and filthy, they become a major source of  contamination to the air in your home. Air filters are supposed to clean the air in your home, not make it worse. If anyone in your home, including kids or pets, are prone to allergies or have asthma, dirty filters can make their symptoms much worse. Second Nature filters clean the air in your home, removing allergens like bacteria, mold, dirt, dust mites, pollen, pollution, pet hair and dander that can aggravate allergy symptoms.  

So, how often should you change the air filters in your home? It depends.

It’s recommended that in the average home allergen air filters should be changed around every 3 months. In homes with pets, children, or people with allergies, changing out filters every 1 to 2 months is best. You may also want to change it more often if you live on a busy street or in a city with poor air quality. If you have lots of pets or severe allergies, it’s recommended to change your air filters every 30 to 45 days.

Second Nature Remembers When To Replace Your Air Filters For You

Changing out an air filter is easy enough, but it’s hard to keep track of when to change them. It’s the kind of thing that just slips your mind. Second Nature has your back. With Second Nature you never have to waste energy trying to remember when or if the filters in your home need to be changed. They arrive at your door and you pop them in. Boom. And no more figuring out what size you need for the hundredth time. Second Nature will send the filter you need to your door exactly when you need it. Easy, simple and convenient.

Fresh Air Filters Can Save You Money On Your Energy Bill

I think it’s pretty safe to say that we all like having more money in our pocket. Maintaining the air filters in your home means your HVAC, otherwise known as heating, ventilation, and air conditioning systems don’t have to work quite so hard. In fact, they’ll actually work more efficiently. This means they’ll use less energy to operate, saving you money in the long run. Using less energy will also reduce your carbon footprint making your home more earth friendly.

Changing Your Filters Can Prevent Expensive Home Repairs

We just talked about how not changing out your air filters regularly can cause the heating and cooling unit in your home to work harder. And it can even cause them to break. And when HVAC repairs are needed, you can be sure you’ll be getting a hefty bill. Regularly changing the air filters in your home can even help extend the life of costly home HVAC systems, saving you from having to replace them more often. The Second Nature subscription makes it easy to keep everything running smoothly and that means more money to spend on fun stuff.

They Carry Every Air Filter Size You Might Need In Three Different Grades

If you’ve ever gone to the store only to buy the wrong air filter or find they don’t even carry the size you need, you probably figured out that air filter sizes can be more complicated than one would think. The truth is that air filters come in many different sizes. Second Nature carries them all and can make custom sizes if needed for a small additional fee. No more hunting for the one you need. Also, depending on your health needs, Second Nature carries filters in LiteAllergen, MicroAllergen, and SuperAllergen grades to suit every home.
