Fantastic company. I’ve been buying their HVAC filters for years and they are high quality and effective. Their service/support people are great. They have hard to find filter sizes. They deliver very quickly. And their return and refund policies are so easy. I highly recommend Discount Filter!

The filters are not labeled. My previous purchase I ordered Merv8 filters. Every filter was labeled Merv 8. The filters I received were blank. No label.

Absolutely wonderful. We have bad allergies due to the dust and pollen from nearby ranching and orchards. This filter has done so well that we are no longer having to medicate ourselves in our own home. The dust on the furniture has also been reduced which is a major plus. I would recomend this to anyone who suffers from allergies or just wants a clean home environment.
