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.

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!

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

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

After using these for six years, the inside of my AC unit is almost as clean as when it was installed.

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

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.

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.

These are good filters. We have 3 long hair dogs in the house so we change the filter every 6 weeks or so. So glad that Sam's Club has them for a sweet deal!
