Blueair Pure 211+

Coverage Area

Both of these filters are about the same price, so you might expect them to have nearly the same coverage area, but there is actually a big difference between them. You should consider the coverage area when placing down air purifiers because this tells you how much space they can effectively clean.

Medify MA40 coverage area is 840 square feet. That’s very good as it can easily clean one large room or multiple rooms at once. Not only that, but many people use this as their main filter while using one or two smaller filters to cover the whole house or apartment.

Blueair 211+ coverage area is 540 square feet. That’s significantly less than Medify. At the same time, there is one benefit to Blueair Pure 211+ that Medify doesn’t have. Blueair 211+ Pure has 360 degree air purification with its unique filter. Medify is like most other purifiers and primarily cleans from one direction.

While Medify is definitely the winner, some people might like how Blueair 211+ cleans the area more equally.

Medify MA-40 vs Blueair 211+: CADR

Clean Air Delivery Rate, or CADR, is a metric that allows you to objectively compare different air filters. This is a measurement of how much volume passed through the filter and it shows how well it removes harmful particles such as dust, dander, smoke, and more.

A good CADR is usually above 200, but that doesn’t tell you much. It’s best to know how much CADR you need for your room. In general, you want to ensure that the CADR is at least two-thirds of the area of your room. So, if the area of your room is 300 square feet, then you want a CADR of 200 or more.

A higher CADR is always better. While it often costs more as well, this means that the filter is cleaning the air better.

There is a difference in CADR here, but it’s not quite as significant as with the coverage area. Medify MA-40 CADR is 380 while Blueair 211+ CADR is 350. Both of these are amazing as they will both quickly remove harmful particles from the air.

While Medify wins here, it’s so close that it’s basically a tie.

Blueair 211+ vs Medify MA-40: Filter

The filters here are very different. While both are highly effective, they were made with different properties in mind. Let’s cover them in detail.

The Medify MA40 HEPA H13 filter surpasses normal HEPA standards and removes 99.9% of harmful particles from the air. This includes dander, dust, viruses, smoke, and more. There are two filters with three layers of protection each. This ensures that it captures nearly every particle in the air, making it a highly effective system.

The Blueair 211+ filter isn’t quite as effective, but it’s very close. Their carbon filter removes 99% of particles like pollen, viruses, dust, dander, bacteria, and mold from the air. It’s a small 0.9% difference, so they are both amazing. This also comes with two washable fabric pre-filters. These provide further protection, and being washable means that you won’t have to regularly replace them.

Like with CADR, Medify is technically better, but it’s by a fairly small margin.

Fan Speeds

Unlike the last two sections, there is a big difference here. Many people like buying air purifiers with multiple fan speeds. This allows you to reduce the speed to save power, or increase the speed for better performance.

Medify MA40 has three fan speeds that are all accessed by the touchscreen on top. Simply push the button to change the speed. It’s very easy and you’ll love having control of the fan.

Blueair Blue Pure 211+ only has one fan speed. In fact, it only has one button. There is a big circle button on the front that turns the purifier on and off. While this is a simpler system, it does reduce how much control you have over the filter.

If you always find yourself putting the air purifier on high, then they are probably about the same. If you like adjusting the speed in order to match the room’s needs, then Medify is the better purifier.

Special Features

You’re going to see a big difference here as well. One filter has lots of extra features while another one has almost none.

Medify MA-40 is packed with features. It has a timer that ranges from 0-8 hours. This is perfect if you’re sleeping and want to keep the purifier running, or if you only want it to run for a limited amount of time. The purifier also has a child lock, touchscreen operation, and ionizer technology to ensure clean air. It also includes a filter replacement indicator so you’ll know exactly when to change the filter.

Blueair 211+ has the easy single-button operation and the two fabric pre-filters allow you to switch the color of the filter. You can have either the black or blue one in front, which allows you to change the purifier’s appearance.

Medify has better overall features, but it’s nice that Blueair allows you to change its color. Those who want an aesthetically pleasing purifier might really enjoy how Blueair looks.
