Great reliable company for great filters!

The filters I ordered were great. The size was exactly as advertised, filter size and actual filter size. Other companies I have tried have not met this requirement. I have tried getting the 10x10x2 filters at other places and I am so happy I found a company that I can rely on getting what need and the correct item. The other companies fall short on their product being the actual size they advertise. The Merv 13 filters are great. I highly recommend Filter King for all your filter needs.

Thank you a thousand times.

I was assigned to hunt down this particular size. Your company was the only ones that stock this size. Luckily you were also at a great price and offered a subscription program. This program will help us keep our air conditioning units running in a healthy manner when they are most needed. During the Arizona summer. Thank you for your execution and follow up. I will let others know that you are the king.

GOOD PRICE AND FAST SHIPMENT

Just had two new air conditioners installed and I chose the 2” filters to install in the air conditioners. Excellent price on filters and shipped quickly.
