Medify MA-40 Air Purifier with True HEPA H13 Filter | 1,793 ft² Coverage in 1hr for Smoke, Wildfires, Odors, Pollen, Pets | Removal to 0.1 Microns | White, 2-Pack

I got this in a two pack, perfect for their home. 3 dogs, a cat and a horse farm. On top of that a husband with allergies. They LOVE it. One up in the bedroom and the other in the main part of the house. My brother in law says it is great! Makes his life a lot easier. Quiet, medical grade purification. Nice build. Stylish, and no dog or cat smell. Air feels fresh. Thinking of getting one for my daughter as her boyfriend is allergic to cats and has to use Benadryl to hang out at her place. So yeah I’ll be buying this again!

Pros:cleans the air, like you can taste the cleanmoves the air, nothing stale and more air gets cleaned.has an ionizer, makes the air feel fresherCons:Filter replacements are a premium for someYou want to leave it on all the time because it does a job, but filter will go quicker , then see con 1The reviews stating that it’s noisy, I don’t really put it higher than a box fan or or high powered fan moving air around. It becomes white noise very quickly.We have a 3100 sqft house. We bought the 2 pack for a nice deal. About 150 each total. Two pack is a better value for sure.Put one up stairs and one down stairs in the most open areas. I love to crank them both up to high and let them cycle the air in about 2 hours or so. Whole house. Many guests have, upon walking in, notice how “clean” the air feels.We leave it running on low but tend to let it run before bed time on max.You won’t regret it, if you have thing about loud fans, then maybe it’s not for you.

We have a 3700 sq. ft home. With three kids and 2 long hair border collie dogs. In Houston, allergies are a common problem week to week. Also, the humidity adds to the stench of the dogs going in and out of the house to use the restroom. So I bought two of these units. One stays by the stairs and the other moves between the living room and kitchen. I swear, after two days of constant use, my wife and I can tell a huge difference. There hasn't been a heavy or thick feeling of the air since I bought these. The lowest setting is super duper quiet. I would compare it to White Noise used for sleeping. I like how the unit has a 1, 2, 4, and 8-hour timer. I have mine set to 8hr constantly. After a full week of constant use, the unit is still quiet and shows no signs of wear and tear either visibly or audibly. When you place your hand at the front of the unit, a respectable volume of air filtering out of the purifier can be felt. I've had my two units for a week now and I'm more than happy with them. They have done the job that I needed them to do which was to filter the air in my home to a consistent fresh/clean scent and feel. If you're having a tough time deciding on this purifier, I would say just buy it, try it and see how you feel about it after a weeks time. I think you will be satified and relieved.

I have used two of these for 6 months and changed the filter once.My allergies have gotten significantly better. I run it on low instead of sleep mode. Medium when cooking. High when cooking smelly things. Off when spraying for bugs.I cannot recommend these enough if you have allergies. I don’t know much more to say. The noise level is quiet and the sound is not bothersome if you want to take a nap.There is a CADR calculation for the size of your room. Keep in mind the calculations are for max speed. So cut it in half if you want to run at medium speed.CADR= (air changes per hour) x (length) x (width) x height) x 1/60.That is in CFM. 2 ACH for normal conditions. 4 or 5 for heavy allergies. 8-10 for heavy smokers or contamination.It is effective to have in a large room but from one room away, about 25 feet, it gets rid of smelly fried cooking. I use one in a master bedroom / bath. Then another on its own level in an open floor plan.It is nice refreshing air to use for a fan also.

At first they had a very, very light plastic smell. After a week or two they have no smell. According to my pm 2.5 meter, they do a good job cleaning the air.One thing though, if you want to leave them on overnight there's a 'sleep' mode that turns the light on the controls off so you can sleep with it and the light doesn't disturb you... but sleep mode is also low power mode. What if I want it to be on high all night? Then I have to find something to place over the control panel to dim the light coming up from it.Small issue, but it is what it is.

Works as it should. Bought 2. One for me (i already had one) and one for my daughter. Have bought 4 in total. Great product.

10 months in and both units I purchased have seemed to have issues. One has a constant clicking sound and the other no longer works / spins in the low setting. Contacted support and they were of zero help claiming since I did not purchase their brand of replacement filters that I was liable for their product failing… Let’s be honest, a non brand filter that Amazon recommended would not make it so the unit works on medium and high setting but not low… The company instead once contacted wanted to me to join their automatic filter program to keep the warranty at double the price. This is not a company that stands for their own product whatsoever. It’s sad a fan can t even last 1 year and the company won’t honor its 1 year parts and replacement contract without forcing you to join their automatic filter replacement program. Shame on you Lou who works for them in their customer service chat for trying to pull a fast one on me.
