Second Nature Filters Reviews: Customer Experience

Positive Reviews

Satisfying service

JD and Christen are satisfied with second nature and call it the best. They said they were very knowledgeable and accommodating. They would highly recommend the air filters for business and home uses.

Super convenient

The company is convenient because they change filters regularly. It’s cost-friendly, and they deliver to your home, so you don’t have to keep dates when you expect the next filter. They have all kinds of filters, including the odd sizes that are hard to find in other stores.

Great for a forgetful person

I’m a happy client most of the time, I forget, and it would take long before I could change the air filters. Second, nature ships air filters in time, and I can now change the filters regularly. The filters I use are difficult to find in stores, but I can find them at Second Nature.

Negative Reviews

The client never corrected the number of air filters

I paid for something that I never got. Although I voluntarily signed up for the Second Nature service, I never received what I had ordered. I didn’t get the right amount of filters I wanted for my home. I felt it was a throwaway of their money because they never refunded me.

Late delivery

When I  started with Second Nature, their services were excellent, but as time passed, the services declined. It’s two months, and Second Nature hasn’t delivered the air filters. They are still charging me on my credit card, but I haven’t received the filters, and there is no way I can contact them.

Summary: Does It Worth It?

Yes, it’s worth it. Second Nature subscription will save you the time of moving from one store to another looking for air filters. More so, changing the air filters from time to time will save you the high cost of repairing your HVAC.
