Filtrete Allergen Reduction 4" Filter, 16x25x4 is rated 4.5 out of 5 by 103.
Rated 5 out of 5 by from Great price! The last AC company that did my yearly maintenance tried to charge me almost $90 to replace my filter, sure glad I said no thanks. I bought this type of filter last year at a home improvement store, this year they were out of stock, so I checked Walmart, and lo and behold cheaper here and in stock.

Rated 5 out of 5 by from filter This is a very good 4" brand of filter. I've used it before and used to be able to have it on the shelf in the store. It worked great to ship directly to store and Walmart had the best price on this item. Just allow a few days from when you need it and ship to store for free. Quick and easy pick up.

Rated 4 out of 5 by from Good filter. Although it is advertised as lasting up to 12 months, I feel the need to replace it every 2-3 months. I have a VERY difficult time removing it from air cleaner, as there are no holes in the filter in which to insert your fingers to grab it for removal. A simple design change would make it more user-friendly. I've found that I have to use a knife to cut a hole in the filter cardboard to have something to hold on to. Also, the cardboard strips on the sides usually get caught in my air cleaner, so as I'm removing the filter, I really have to pull hard, tearing the side strips, as I remove the filter.

Rated 5 out of 5 by from Help for an old house Our house is more than a century old (built in 1888). Dust particles were magnified in the light that streamed through the over-sized windows. Filtrete filters have given us new appreciation for floor to ceiling sunlight.

Rated 4 out of 5 by from Good filter but some issues We've been using your filters for many years and have had one recurring issue. The housing for the filter doesn't have a lot of wiggle room, but it requires and accepts a 4" filter, so while the filter usually slides in just fine, getting it out is a challenge. It's ok if I am disposing of the old one and installing a new filter, but if I have to pull it for any kind of service, it gets destroyed in the process of extraction and that gets expensive when I have to replace a minimally used filter. My furnace company has worked on the housing and done as much as possible to improve the opening. What I notice is that the cardboard framing that contains the filter does not fit tightly and in fact bulges even on a brand new filter. This frame is what gets caught both going in and coming out of the houing. I would appreciate any feedback you might have pertaining to this issue. I apologize for the long-winded e-mail, but I wanted to clearly describe the issue I have with what is otherwise a fine filter system. Thank you, Harry Saxe
