An excellent subscription service for those who need a reminder to change their filters! I am an incredibly forgetful person. I'm embarrassed to even say how long I've gone between changing my air filters. Getting them shipped to me reminds me to change them on a schedule and I've noticed a remarkable difference in how often I need to dust. I love that they also have less common sizes as both my filters are difficult to find in store. I recommend this subscription service to everyone.

Super Convenient! Super Convenient for changing your filters on a regular schedule, same price you would pay at the store but they’re shipped directly to your house so you don’t have to remember when was the last time you changed them. Also great for odd sized filters that are normally hard to find or require trying multiple home improvement stores! All around great company to do business with!

"it's not economical to refund you" Customer support is a joke. They don't email you before shipments are made so I emailed in to get it canceled right after I was emailed about it being shipped and they responded with this. "Thanks for reaching out. We truly apologize for any inconvenience. Once your order processes and ships we are unable to issue a refund or accept returns. As our main expense is shipping, it is simply not economical."

Clean Air for a Healthy Home If we've learned anything in the Covid-era, it should be the importance of clean air. Its good for your HVAC and its good for your lungs. One of the best things you can do is change your filters regularly. A subscription from Second Nature takes having to remember when out of the equation. Filter arrives on schedule and you install it when you receive it. Keeps your equipment running and keeps the air you are breathing cleaner.

I use second nature for heat/air & refrigerator I use second nature for heat/air filter and water filter for refrigerator. The filters are always high quality and fit like they are supposed to. The filters also work like they are supposed to. You can custom set the dates for your specific needs. For me, it is every other month for heat/air and every six months for refrigerator water filter. Then I never forget to replace them because it is always time to do so when they arrive. The pricing is competitive with the market. I love the second nature experience!
