I really like getting the reminders letting me know it is time to change the filter! I sometimes forget and that e-mail keeps me up to speed on changing it. They are very good filters for a good price.

The filters received are not up to the quality of the first order I placed with your company based on a side by side inspection. I may have paid more for the original Accumulair filter order. Inspections of my air handler by a professional HVAC tech revealed that the Accumulair filters did an outstanding job. I fear this last order is of poor quality.

The filter is slightly under-size which allows a very noticeable whistling sound. Rotating works briefly. Have not found an easy fix.

I have an odd size filter and couldn't find it at the local retailers. I found Discount Filters thru an on-line search and I am completely satisfied with both the product and the service.
Ordering was easy, recieved my order within 2 days and the product works great. I'll never buy filters from anywhere else in the future.

Furnace takes odd size filters (18 x 18 x 1) which you can not find in retail sources, so this is the only way to get those filters.

Use the filters in my home. Apparently I have a hard to find size (18 x 18) and was so glad to find them with you. Service great, delivery great, price great, product great.

For better indoor air quality (IAQ) consider running your system fan continuously, or install a thermostat that has a "circulation" or programmable fan function.
