The filter I recently purchased

The filter I recently purchased has been great. Air quality in my house is great. Very few allergy issues. The air flow through them is quiet compared to the previous brand I had purchased. Definitely going to stay with Filterbuy.

Good filters, but I think I agreed to future deliveries. I have more than enough and if there were future filters ordered I need to cancel that. Thanks
