Blue Pure 211+ Air Purifier with 3-Stage Filtration System

George Kefalas: I like that this air purifier is quiet when it is in a low to medium setting. However, at a high setting, it does become it bit noisy.

Lane: Bought when the forest fires were burning through alberta this spring. Filters out the smoke smell. Left it on in eco mode. Very quite. After 2 weeks, I found that the air particles I seen in the sunlight were all gone!

It did an incredible job. As an important side note, I live in a house without children or pets. So might have to ask other customers with these factors how it would perform.

But very pleased overall!!

George in Canada: This air purifier improved air quality discernably in our 2-bedroom condo during the recent choking wildfire smoke. Glad we bought it. Very quiet in night mode and acceptable during higher settings. The HEPA filters can be replaced easily however they are still okay after about 100 hours of use in the medium speed setting and with closed windows. The touch controls are neatly integrated and unobtrusive however we would prefer simpler ergonomic buttons or nobs located on the side because it is not easy to find the right setting without numerals or idiot dots. Please redesign the controls to earn 5 stars.

JohnnyBJohnnyB: Purchased a 211+ and x4 411 units in February of 2020. Just purchased a second 211+ in August 2023. All 5 previously purchased units still work perfectly after over 3 years of continuous running, only turned off for cleaning. The blue and/or gray pre-filter needs vacuumed off about once a month with a furniture brush attachment. The 411 units are top-heavy and have all been knocked over multiple times by pets and kids in 3 years, but continue to work just fine. The red change filter lights do not all come on in the same day, but within a week of each other usually, after about 6 months. We have one in every main room and bedroom and they have greatly reduced dust and other allergy related air issues in our home. They are a very quiet on low, a little noisy on medium, and very noisy on high. We turn them all on high when cleaning the house. We leave them on medium most of the time, especially in rooms we aren't using. Ran on low in bedrooms at night. My only complaint is the price of the replacement filters is a bit high, but our family feels that it is worth it. Photos are new filters next to dirty 6 months filters.

Candice G: I really loved this air purifier for the first 7 months. Then around the 8 month mark it started to give off a very strong and unpleasant smell. Almost like an animal died in it. The lights were still white and did not suggest the filter was in need of a change. Upon checking the filter, I saw that it wasn't even that dirty. I removed it and ordered a brand new one to see if that would help. Unfortunately it did not. The same smell persisted. It got even worse the higher I ran the fan setting. Again I took out the new filter to smell it, wondering if it had some residual smell as some say they do. nope, not even a whiff of the same smell. Completely odorless. I can only guess that the smell is coming from the motor/fan portion in the upper part of the unit. The customer service reps have not been very helpful at getting back to me or offering a solution. I really wanted this to turn around. It now seems that these models no longer exist on the website so they may have phased them out based on others having the same issue. Any advice on better units that actually work would helpful! It's a crazy market out there with the many brands to choose from and high price points.

A. Pedersen: This is a review of the 211+ (not auto) product.

I purchased this to take the place of a Winix 5500-2 that I moved to a smaller room. I did a fair amount of research before deciding on this model. I wanted something under $300 that could filter a larger room. Consumer reports and the Wirecutter both rating this model very highly (in the case of CR this model was only beat out by the Blueair Classic 6XX model and that one goes for nearly $800 right now and is only somewhat more powerful.

The unit is very simple. It’s a large fan in an attractive white housing with a slightly larger white plastic base that houses the main filters inside. There are two different colors of the washable external cloth filter in the box. You can use whichever one you prefer. My unit had a reasonably bright blue one and a dark gray one. It’s nice that they give you 2 of them. They only give you one of the large internal filters.

The power cord is attached to the back of the unit, so if you break it or a pet chews the cord, the whole unit will have to be replaced. That’s a shame.

The unit itself is made mostly of plastic, which makes it light and easy to move, but it...

Sam: Initial impressions of this purifier are very positive. I'm not setup to test the actual purification abilities beyond an anecdotal indication that it seems to clear the air well. See the reviews on Smart Air (they think it works very well but is over priced), Consumer Reports (the 211 and the Classic 605 are their two highest rated units), and elsewhere. BlueAir is very well regarded in terms of actual cleaning effectiveness.

For all the other features, here are some of my key decision points and useful tips:

First, I bought both a 121 and 211+ - they have similar specs, except the 121 has a 400 CADR rating rather than a 350 for the 211. I was a bit surprised to realize that they appear to have identical motor and fan units - you can swap them back and forth, and they measure identical power consumption, and sound the same. This means the 121 gets the slight boost by simply being taller and holding a larger filter. More filter area would make for more efficient filtration, and a small boost in CADR rating.

This isn't really a knock, it is just worth noting if you are considering both units. I would say the 211+ is the better value in this regard, the 121 is...
