Too bad ours only come in 2 packs. When you add 4 2 packs it doesn't apply the discount. Stepped up to the next filter up and added 4 to cart. Only discount I see is the $25 off $100. It isn't applying the 20% to 16x25x4 filters.

I'm also only seeing 15% advertised after following that link and actually clicking the shop now button our size doesn't come up which is why the discount doesn't apply to my cart. So this is for select (1") filters only.

Unfortunately, though the deal description by Lowes doesn't say this, it appears that the deal is only for 1 inch filters. Unfortunately, not 4 inch even when sold as single packs.

It is a good deal though if you have 1 inch.

It worked for me, got 7 1900 filters just now. Thanks!

Also there's a rebate on Filtrete's site if you buy 4 or more for another $12 back.

i bought these last time lowes had the twin packs on sale. they cost me about $5 each (Before rebate). this deal worked out to a little more, about $7 each but still a good price for a decent filter.

I'm not too familiar with filters...but for the 1900, since it filters so much, does that mean it also would drop the airflow significantly?

this question appears every time there is a deal on these filters. the answer is no.


the thing to remember is that per unit area, yes these will be more restrictive (than a cheapie filter), but they have A LOT more surface area so that the total effective "open area" is comparable.


a major thing to note is that since these do filter more you do need to change them more frequently. if you do not, then the airflow does become an issue. the good news is that is is really easy to see when these get "dirty" as the entire surface will have dust build up on it.

Be careful when you pick these up that the price on the receipt is the same as your confirmation. Did some deal stacking with the 25 off 100 over the weekend and they took off the 25 coupon when I went to pick it up.

Yes. The higher the filtration capacity of filters (higher MERV, FPR, MPR) the more airflow is restricted. This is true when all other variables are the same (i.e. 1in thickness and number of pleats). If you go from a non-pleated to a pleated filter (with same MERV, FPR, MPR), it should be less restrictive because you are adding surface area. Same as is you go from a 1in to a 2in filter. Now, if you go from a 600 MPR to a 2100 MPR, it will definitely restrict airflow, even when newly installed. Typical recommendation is to not exceed MERV 8, which I believe is equal to FPR 4 and MPR 600, and replace the filter every three months. I replace them monthly.

Pretty good explanation, I've been buying MERV 8 filters on amazon and they recommend changing every 3 months. I usually get a 12 pack for about $60.
