Great filtration in my home with three dogs and I will continue to buy in bulk when I need!

First of all the last time I ordered it it took almost 2 weeks to get to me. I honestly was not going to order it again, but I did, but I think they’re good filters. This one came in just a couple of days so that was great. They say that their medical filters or something I’m not quite sure what that means but yet they don’t look many much different from the regular filters but they do last long almost 3 months. I can keep one in the price is fantastic

Air appears to be cleaner since installing filter. Traps odors and dust. I stop sneezing when the AC charged on.

I have used these filters in the past, they help to keep the ac unit clean. Great for the breathing air also. I change the filter every two weeks. Works for me.

We have been using AIRx HEALTH Air Filters for over a year. When my HVAC company came a few weeks ago to do their annual inspection, they commented on the "pristine" cleanliness of our furnace. In all my years, I have never had an HVAC employee comment in this manner and must credit it to Discount Filters and their products. Yes, they are a bit expensive, but they seem to be taking care of our HVAC investment.

Great product at the right price. Performs really well.I wouldn’t change anything about them. Just perfect.

I love this company, however, maybe we just input the quantity wrong or something. The purchase of 12 filters is cheaper than 6. That being said, we were charged the full price of 2 boxes of 6 instead of the price for 12. I will certainly watch the numbers if we order again.
