Filtrete 16x25x1 Air Filter MPR 1200 MERV 11, Allergen Defense Odor Reduction, 4-Pack (exact dimensions 15.69x24.69x0.81)

Effectively reduce food odours.Highly recommended

First some facts that aren't listed in the product description, packaging or website.This is a pleated particulate filter that has activated carbon impregnated on one side so it both filters the air passing through it of particles and the carbon helps rid the air of odors.I contacted Filtrete and was informed that this filter has an equivalent MPR rating of 1000, MERV 11 rating, pressure drop of 0.24 and is 90% efficient at reducing particles 1 to 10 microns in size.My Experience:I got this filter because of some recent home improvement projects that created a lot of fine dust and odors (paint, cleaning solutions, building materials). I normally use the Filtrete MPR 1000 filters. Overnight there was a significant improvement in odors after using this Home Odor Reduction Filter.Concerning Dust:Your HVAC system is not a vacuum cleaner. Running it 24/7 with the best filter in the world will not eliminate the need to dust and clean your home. Much of the dust that settles in your home is too heavy to be sucked up into the air return. Especially if it's far away from the return. These filters work better on lighter dust floating around the air so you breath less of it. For example, I've cleaned pet hair out of the filters for my air purifier and even from the filters on my computers but have never seen any pet hair on my AC filters. The HVAC system just doesn't move air enough to lift pet hair 8' up to the ceiling. Think about it. When you dust a room you don't just stand in the middle of the room holding your vacuum cleaner hose up in the air so it can collect all the dust in the room. You have to pass it over every surface. Why would you expect the lower suction of an air return that's not even in the same room to do it? The filter will clean the dust floating in the air that doesn't settle and prevent it from recirculating.If you have serious allergies and just using a different HVAC filter isn't enough, you're going to need to get a good quality HEPA air purifier and try and reduce entry of allergens into your home.You're still going to need to dust and vacuum regularly so don't throw out that feather duster and french maid outfit just yet.Concerning Odors:Activated carbon has been proven to absorb all sorts of odors. The odors get trapped in the carbon like a sponge but just like a sponge there is a limit to how much can be absorbed. While this filter has significantly more activated carbon than other similar filters and will help reduce odors don't expect it to perform miracles. Work on eliminating the source of the odors first and let this filter help out when necessary.Have cats? Keep the litter box clean. Have pets, bathe them from time to time and vacuum frequently. Have mold? Kill and remove the mold and find and fix the moisture problems. Have foul cooking odors? Use your range hood when cooking. Smoke? Don't do it inside, better yet don't do it at all and wash all surfaces of your home because smoke particles get everywhere. You get the picture. This odor reducing filter can help with any odor problem you might have but you can't rely on it to be the only remedy.Pressure Drop:Most HVAC systems are designed around certain parameters. System pressure is important so that the system, especially the blower motor in the air handler, is not working harder than spec. Air filters are traditionally used to keep big dust particles from causing problems for the components of the system, not to clean the air for you. Pleated filters have more of a pressure drop than the cheap fiberglass filters and lower MPR filters (MPR 600 is 0.14) and the 0.24 of the Odor Reducing filter is among the highest of the Filtrete filters, equivalent to the MPR 2400 Elite Extra. Many people, including myself with a very old AC unit, use these types of filters to help clean the air without issue. If you have any concerns with an older HVAC unit you might want to contact your HVAC contractor to come to your home and analyze your system. Keep in mind that many do not favor pleated filters even before measuring static pressure and some will try to sell you an expensive electronic air cleaner, which to be fair many work really well.Since these pleated filters also keep the air passing through the air handler and ducts cleaner they can also help reduce maintenance costs though. As filters become clogged the pressure drop increases so it's important to change your filters regularly. How often depends on the air quality in your home.

Great. Besides harmful gases. Is much better at catching regular dust than standard filters

We had our house termite tented 16 days ago, and somehow an animal got into the house or walls and died...with an overpowering stench in our master bedroom. I bought the two highest rated smell killing products on Amazon, and they barely made a dent in it with the whole house fan running full time outside air through the room.We were REALLY desperate, because hotter weather was coming, and pushing humid outside air through the house wouldn't be great. I got the 4 pack of these, along with a single locally. I made a simple 4 sided box with an open bottom and a fan to draw air through with a baffle to fit the fans output, and installed the other one in our HVAC system.I shut down the whole house fan and shut the windows, and within a minute or two the smell was nearly unbearable. I installed the jerry rigged, packing tape sealed box...and to my astonishment...within 2 or 3 minutes the smell was almost gone!It took me a while to figure out placement, but 6 days later with the fan running on low/medium 24/7 it's still sucking out the stench! This is all way out of its normal use, but HIGHLY recommended for it's ability to remove odors...I can't believe any odor could be worse than this. I'll be reusing these as regular house filters when this nightmare is over!

Bought a 5 yr old hse that had a dog. Got rid of doggy smell in short order. Too expensive.

I change my air filter every month, and these Filtrete MPR 1200 filters are excellent. They fit perfectly, trap dust and allergens well, and even help with odor reduction. The quality is consistent, and they do a great job keeping my home's air clean. Highly recommend for anyone looking for a reliable filter!

Filters for our furnace their working great.No longer have the light dust showingon table tops. As long as you change your filter on your schedule you will not have dustproblems.

These things work great. It’s hard to describe, but I notice it’s working when the house has a very neutral smell. It’s almost a negative smell profile, total lack of odor. I have a dog and it clears that up along with other odors.I will say, the effect started to fade before the end of 3 months. I actually decided to change the filter a bit early to get back the deodorizing effect.I saw a recommendation to put a used filter outside in the sun carbon side up as the UV rays are supposed to release the odor and renew its odor capturing ability. I did this for the recommended 15 minutes, but can’t say I noticed it worked. Next time, I’ll try for a longer period.
