I suffer from multiple chemical sensitivities which effects my respiratory system. These filters not only remove dust particles but they also filter out chemical odors. I have used them for over 20 years and am convinced they have prolonged my life. Thank you for making this excellent product available to me!!

I really haven't used the filters as of today; still using an old one; which will be replaced this month. Will advise later on the progress. I imagine that the filters are going to work just fine.

I use this filter because I have a dog and it seems to do a good job. The people who cleaned by A/C ducts commented that this was a really good filter so that made me feel like I was getting my money's worth.

These odor air filters with carbon are difficult to find in my area, so when I discovered discount filters, I was thrilled. I have never been disappointed in the price, promptness, and quality. Once I did received a damaged package, but it was quickly replaced. Thank you!

Wife has allergies. Purchased these to help and to keep household odors down Cooking, cleaning etc. haven't been in long enough to give overall opinion right now. I do recommend their refrigerator water filters in multi pak's. Work great and good price.
