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!

The filters are fine but Fedex delivers… The filters are fine but Fedex delivers them damaged and I have to call and have Second Nature send me new ones 2 times in a row now. Stop using Fedex!!

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.

I have mild asthma..... I have mild asthma and recently moved from Washington state to southern Oregon. The climate in Oregon is somewhat drier and dustier than the Puget Sound region in Washington. I love having my furnace filters delivered on a regular basis, knowing that my home's air circulation is always being efficiently filtered. Also, that I'm getting clean, filtered ice and water from my fridge with a clean filter every few months. Thanks, guys!!!!

"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."
