Have used Filtrete filters for over 30 years and have gradually moved up the ladder to a better grade of filter. The 1900 is outstanding in performance and has even reduced the amount of dust circulating with in our home. In my opinion the cost is on extreme high side for a product made of the materials and quantity produced per production run. As of now it still is the best filter on the market.
I have severe allergies. Filtrete was recommended by my allergist. They have a lager variance in protection levels, 1900, 1500, 1050, etc. We use the 1900 and change once a month. Not only are we breathing better, we are dusting less. Love it!
We have been using Filtrete for about 3 years, we have 2 cats and I have seasonal allergies. I can tell a big difference with my allergies. I would recommend to everyone.
Coming from the Industrial Hygiene field I know a little about filtration and most importantly about Indoor Air Quality (well, to me at least), these filters are widely available and very easy to differentiate in type, function, length of service, and sizing. I absolutely love the illustrations/pictograms on the cover, thus facilitating in ease of purchase. Job well done.
I used to use these filters in my furnace. I loved them. Now I need them in a custom size and Filtrete no longer offers that service so I am very disappointed. I need two different custom sized but alas and alack have to go with an inferior product that fits.
