the filters work very well act "catching" dust and hair and very economical since we only replace them every 3 months.

Great value! We need the extra allergen filtering provided by these filters to help with family allergies. These do not dissapppint.

The filters are marked 20x30x1 but they are actually a bit larger than that. I have to slightly bend them and force them into my filter holder. I am thinking about returning the remaining filters.

I have been using these filters for about 3 years. I was buying them directly from Filtrete but I have found they are available at Sam's for a lower price.

So far, they have worked really well with my existing AC system. In fact they have cut down the dust in my house by a big margin

Excellent filter! You will have to change it out more often, but I feel it is worth it. And at this price, the price per filter is excellent!

It is awesome way to take care of unwanted pollution, germs, and viruses. Change it, as suggested, let it do its function, feel the results.

Honestly I've been using these for years. The filters are work great! Love the ability to buy in bulk.

I have been using these filters for many years. Sam's Club is the most economical way to purchase them using Instant Savings.

The size printed on the filters I bought were not true to size. They were too large and we could not get them to fit. I took them back and bought filters at Home Depot. Perfect fit.
