Amazon has the 6-pk. 20x20x1 Aerostar air filters for $28.49 with Prime shipping. [amazon.com] These have a MERV rating of 11 so equivalent of a 3M fitrate rating of 1000-1200 so good for allergies but at 1/3 of the price so I think these are a great deal. Note these are built sturdier than a 3M filter but are slightly smaller measuring 19.5 x 19.5 x 0.75 inches while the 3M filters are 19.7 x 19.7 x 0.75 per a review.

Reference for MERV rating in relation to 3M MPR https://www.iallergy.com/pages/co...te-filters

*note this ships in a clear pack unless you check the box to use Amazon shipping during check out to get it in a box so the item isn't as visible

This appears to be the same price as usual? Or am I missing something?

Don't just throw these in your furnace...Merv 11 is very restrictive for airflow, not all units will work well with this. Some won't even allow this type of filter.

I wouldn't use these on my furnace but they are great for strapping on a box fan for an air filter.

Seriously, massively help seasonal allergies or reducing particulates in air if near a forest fire.

from https://www.directenergy.com/blog...ight-home/

"A decade ago, it used to be that if you had an HVAC system that used panel filters rated 6 through 9 MERV, putting in a MERV 11 or higher filter would restrict airflow (known as filter pressure drop). In turn, this would lengthen the system's run-time, adding to your heating and cooling costs.

This assumption is not entirely the case anymore. Newer pleated filtering media increases the filter's surface area so that while the filter might be finer, there's more area for air to pass through. The more pleats per foot, the better. The thicker the filter, the more surface area per pleat.

So, while the filter pressure drop issue still has some impact, a 2009 Home Energy experimental test concluded that "…if no accommodations are made for the greater pressure drop of high-MERV filters, air flow and energy penalties are not likely to be severe — at least, not until the filter is loaded with dirt.""

Good find IMO. Got a different size, but Repped nonetheless.

I just moved into my first home. Would anyone care to assist a new homeowner on whether or not this is a good deal for a 20 x 25 x 1 Merv 8 filter for $24/6 pack?

Same size I use for my system 20X25X1. There was a daily deal at Home Depot yesterday $20 for a pack of 4. Lowe's had a pack of 2 3M for $18. I just installed the last filter I had so I'm looking for a deal. I think I should have picked up the HD deal yesterday.

I use 4 inch thick filters because 1) they last longer and 2) they have better air flow with higher MERV ratings. A MERV 11 in a 1inch is much more restrictive vs a MERV 11 in a 4inch thick filter. If you can fit a 4inch filter in your box I highly recommend it. You'll notice a difference in the airflow and runtime of your furnace. Just saying

I'm just here to double up on what FearAndloathing said.

Just bought merv 12 for 42 bucks! damn.. I did see merv 11 at $32 reg price but the filtration i think is far different. from what i researched. the differnce between 11 and 12 is quite a lot. thats why the price increase is significant.

Very true but the key is loaded with dirt. Many home owners forget to change their filters on a regular basis and that is where you'll really start seeing the issues sooner than you would with a lower MERV rating. This of course is no fault of the poor filter so you can't blame it.

Also the duct work is the make or break. If you've got duct work that can't handle it, I've seen going from an 8 to 11 MERV rating cause all kinds of issues so don't assume you'll be fine.
