Saved tons of money compared to Lowe's!!

My brother told me about Filterbuy when I was complaining about the cost of filters for my HVAC. He has been very happy with the filters from Filterbuy and likes that they are delivered. I promptly ordered six months worth of filters. I noticed a big difference immediately. They are much quieter than the filters I was using by Filtrete. I also learned that during super hot or super cold periods, it's better not to use high MERV or high MPR filters as it puts an extra strain on the HVAC system when it's already working around the clock due to extreme temperatures. Since I started using Filterbuy filters not only as my system quieter, it also doesn't seem to run as often. So I expect that I will save money on my electric bill too, in addition to paying substantially less for filters. Thanks Filterbuy!

Great filters

I tried these after a retailer stopped carrying the brand I used, so I was surprised how great they worked and I change every 4-6 weeks, living in Florida A\C runs a lot. Great product give it a try!

16X 20 furnace filters

The filters are nice, had no trouble getting them in my furnace compartment. Slid right in, others I’ve used had problems getting them to fit. It was a struggle. Like these filters a lot, so far.

Have used them for years at my house. I love it because I don't have to think about when to change my filters. So naturally I wanted to do the same for my office.
