I've been using the cheap local big hardware store filters for years, but have been having congestion issues for the last couple years. I run a stand-alone air purifier, but thought (finally) to try a high quality furnace filter. It's only been a week, but I can tell a difference already.

Im new to the hvac filter game and Filterbuy has made it easy to order the filters I need and even give me the choice of type of filter ! I chose the highest grade because I have dogs and asthma and I love knowing the air is being filtered when the ac or heat is on . Price is very affordable as well .

I purchased and got the filters about a week ago. Oregon is now having guess all over the state. The air quality is terrible. Currently the worst in the world. In Thursday I came home and took out my 3M filter and put in the MERV 13 filter and turned in the fan of my furnace and my oh my, the smell of smoke left out house and made it quit comfortable. I have it run for about 30 minutes every couple of hours and the quality of air improves quite a bit. I have told 4 other people about Fukterbuy. Oh I was also happy about the fit. 3M and Honeywell I always have to bend the filter to get it into the slot. With Filterbuy it the first time

I found out about FilterBuy as a regular listener of the Dan Bongino show, and I have to say I am very happy with this product! There has been a noticeable improvement in the air quality at my place and I love that I can just subscribe to these and not have to think about air filters anymore. Great company and great product! Thanks Dan!

it Fits which is very important as some that is the same size do not. Would recommend them.

I've been on this Earth 65 years with sinus issues these filters are the best I've ever bought.. if you don't buy them.. well go ahead and breathe dirty air!!

I love these filters! I started using them at the very beginning of the Covid outbreak the Merv 15 I believe and nobody in my household has tested positive yet!

Filter are great and the subscription option is great but I wish there were a subscription option for only 3 seasons since we don't use the furnace in the summer and also it would be best if you shipped the two different size filters in one box instead of two.

I have always thought very highly of your filters. I know you say every 3 months, but I think they would last longer because of how they are made. Thanks

I ordered several and buying expensive type for my new system that I have and for some reason they are a little too small. When the system shuts off the filter falls down and makes a sound hitting the cover. I ordered the correct size, so I don't know what is going on.
