AIRDOCTOR AD5500 HEPA and VOC Air Purifier for Extra Large Spaces & Open Concepts with UltraHEPA, Carbon & VOC Filters - Captures particles 100x Smaller than HEPA Standard (AirDoctor 5500)

Does a Great job filtering out dust particles. Our home feels cleaner and looks better. The unit is extremely quiet, that was the most surprising part! Definitely recommend!

Best purchase I’ve ever made for my family & my house! This is such a quiet machine! Love knowing we are breathing good air now!

The manufacturer declares cleaning gases + formaldehyde gas. In fact, the device does not clean any gases, the manufacturer also wrote to me that they declared this without testing! Very expensive + expensive fine filters and do not clean so well, do not clean gases What a waste of money

Setup was quite simple. I followed the included instructions and with in about 5 minutes, the unit was set up and running. It provide various modes of operation and the ability to turn off the lights for night use in a bedroom is a huge plus.

Outstanding air purifier. We purchased one for our nephew and he raved about it, so we got one. Works great

I purchased the largest size and it works GREAT! Cats' litter generates a LOT OF DUST and this unit handles it, no problem. I liked them so much I wound up purchasing 3 of them.

We started our air purification journey on a whim. I have moderately bad seasonal allergies (ragweed and cedar) and it is ragweed season and I just couldn't face another 5 months of allergy medicine with a decongestant that requires me to swipe my drivers license to buy and has a monthly limit of how much I can purchase. Some stores around here only sell 5 days worth at a time and limit 1 package so I end up going to the store multiple times a week to purchase the "controlled substance" that is over the counter allergy medicine. One of my colleagues has been telling me to get an air purifier for years. We started with a small one (different brand) that works for just one room. We put it in the bedroom and after the first night I woke up with both nostrils open and able to breathe freely. My eyes weren't sticky. it was amazing. But that little room purifier won't support our big open concept living space. So we purchased this Air Doctor 5500 and we're very impressed with its performance. We leave it on auto 100% of the time and 95% of the time it is so quiet. We can tell it works because within seconds of cooking we hear it spin up to a higher setting automatically to purify the air of cooking odors and compounds. It is doing a great job filtering ragweed particles from the air. We have indoor / outdoor pets that bring in a lot of these airborne particles on their coats which usually have me sneezing shortly after they come in, especially when I pet them. The Air Doctor 5500 has changed this completely. When it is running it is as if I never had allergies! Total life changer! My only reason for 4 stars instead of 5 is that in the 5000 they had a one air intake and 3 filter system. In the 5500 it is a two air intake and 6 filter system. So they've effectively doubled the number of filters which doubles the annual costs. Those filters have to be replaced every six months on average for a cost of around $250 so it's kind of like printer ink. It's a lot to pay up front and every couple years the maintenance costs are higher than the cost of the entire system. It feels scammy and gross. I see other air purification manufacturers setting their businesses up the same way to price gouge on filters. So I don't like this about the Air Doctor. And the costs to maintain it are much higher than the costs of my allergy medicine. But if we had three or more people in the household on allergy meds: we'd break even. If you're on a budget please take an hour to run some numbers and think carefully about which air purification system is right for you, because they will have no value to you at all if you're not able to maintain the filters. #recommended

Has been great
