Great at cleaning the air!! On maximum the noise level is a bit loud, but the air quality improvement offsets that for me.
I would purchase it again.

Good size hepa filter. It is a bit loud butovertime you get used to it. It would be best to have an indicator to show the air has been filtered. My other hepa filter has the light indicator and it really helps.

As an allergy suffer I’ve always use air filters at home and work. Son move out (great thing) but took an air filter with him so I needed to replace one. I had two Winix filters, one large and one smaller. He took the larger one and left me with the smaller P150. After reading reviews I decided on the Medify MA-40. Thank goodness because the other units would have been too big. On the lowest setting it is noticeable. Sleep mode and low are the exact same so not sure why they are there. This unit has three speeds and low is the only one I’m comfortable using while in the room. The others are too loud. In comparison my Winix air cleaners where silent on both settings one and two. Like other users I consider it white noise and doesn’t keep me from sleeping. I bought the two pack and one was slightly louder so I took that one to work where its louder and kept the quieter winix. If the wife starts to complain about the noise Ill switch it. I like the ionizer and I run mine 24/7. Will update as I use it more.

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.

Pros:
cleans the air, like you can taste the clean
moves the air, nothing stale and more air gets cleaned.
has an ionizer, makes the air feel fresher
Cons:
Filter replacements are a premium for some
You want to leave it on all the time because it does a job, but filter will go quicker , then see con 1
The 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.

So far so good ~ day 1 ~ NOISE level was a bit much for me even on the lowest setting BUT keeping in mind I’m a light sleeper. Love the sleep mode option. My husband has really horrible allergies ( dust , dander , dogs , the list goes on ) and as I work partial nights , he said while sleeping he wasn’t congested at all as he usually always is . I’ll post a follow up review in a week to see the difference as we are a smaller home with 2 boys (shedding always labs) and a cat.
I’ve noticed a difference in SMELLS in the home ( not saying my home stinks ~ but sometimes has that “DOG” smell , especially when coming in from the heat.
PRICE POINT , I purchased the 2 pack MediAir 40 , a little pricey but if it works we will be pleased. I was happy to have found the payment option.

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.
