Not a good buy

Filter is bigger than what was posted and had to cut it down to fit. Will not buy from you again.

Great price for these filters will buy again

Purchased a 3 Month supply for our home. We prefer to purchase in bulk. The price for the 6 filters was cost effective was great compared to our local big box store! The filters fit just as they should. The MERV 11 rating was recommended per the manufacturer, I like that it will support our home needs by filtering out dust and allergens!

Tight fit

Second order where the filters are a very tight fit compared to previous orders. Might be a good thing ensuring all air passes through the filter but it is a challenge to get into the carrier.

Difficult to find filters made easy

My local hardware stores did not stock the filter I needed so I found Filterbuy on line and had a great deal at my doorstep in days. That was easy!

Been my go-to for a number of years!

Never had any problems with the product from these folks. They don’t force you to use more expensive products, what you decide is what you get, at excellent pricing. Not sure which filter quality is best for you, check out their data and make an “informed” decision.
