quality looks good, but I could not use it due to size too big. it does not fit.

Buy the best for a New A/C unit !!

I have had difficulty finding this size of filter in the local stores in anything other than the flimsiest style. This is a brand that I like and it was so much easier to order them and have t hem delivered than spend time trying to find them. I could have ordered from the big box stores, but it was easier with Amazon. They came boxed well with no crimps or bends.

This is the real deal. I received the package of two filters with Genuine 3M packaging of 1900 Filtrate Ultimate Allergen. I replaced a HEPA filter with this product and immediately experienced a much cleaner air flow in my house with particulate, VOC, and Mold spore problems. I love this filter!

Ive tested a LOT of filters over the years for shop air filtration systems. THIS filter is the only one that gives very low flow resistance (lower than most MERV 8 filters) but, at the same time, it offers 94% filtration efficiency for particles > 0.5 microns. The secret is that this filter has about 2x as many pleats as every other filter Ive tested so it has about the same filtration area as a 4 filter. Thats how it gives the best of both worlds... low flow resistance like the cheap fiberglass filters and high filtration efficiency (MERV13) at the same time. I wont use any other filter from now on. Kudos to the 3M engineers who put this one together.

I have a high velocity AC system which has this size of filter. The filter that was installed was a different brand but still a 14x30x1 like this. However, the actually dimensions of the two are slightly different (i.e. 1/8 off). This made it almost impossible for us to put the filter in. Ended up squishing it slightly to make it work. Well have to find something else after we use these two.

I only use filtrete filters and the 1900 I can’t find locally so order them. These keep the air clearer and keep the dust down. Got the two pack for a great price.

Blocks out dust, smoke, bad vibes, haters, your ex. Everything! Get one on your HVAC System and get a 20x20 filter and slap it on a 20x20 box fan with some adhesive for a portable air purifier :)

This product arrived on time in pristine condition. It was very easily installed. I will most likely order it again.
