Always bought these AC filters at Sam's when on sale. Good value and it works. Online site shows all the sizes. Free delivery via UPS or FedEx for Plus members. Recommended.

These filters cut dust and allergens down immensely in our home. The down side is they restrict the movement of air thus making the central air unit work harder.

These Filtrete filters are wonderful. They last longer than the cheaper ones and they are very sturdy. The air smells better when I use this filter. They do cost a little more but are very much worth the difference in cost.

These are great filters. They are thicker and sturdier that other ones. We change our monthly and they capture the dirt and odors. Cost is the best compared to home stores.

I am always cautious about buying filters by mail because the carriers often destroy them if they are not packed carefully. My filters arrived in perfect condition and I install them immediately without any problems.

I usually buy the filter with less coverages, because I do not need the additional coverages, so I had to spend more money. My income is limited. I believe you should have more than one option to choose from.

I like this product. Seems to catch more airborn particulate than the cheaper filters. I have 2 rambunctious kittens, always stirring up dust bunnies while playing.

We found not many places carry filter size we need for new home. We can get excellent filters on sale price right here and delivered to home at no extra charge.

Great price, especially when on sale, and worth buying four at a time. I've purchased in the store as well as having them shipped and they arrived in great condition.

Just in time for the start of our spring allergy season as I clean the tree pollen off of the car. I typically use the dust grade until the allergy season arrives. These are an excellent upgrade to capture finer allergens.
