If the Best Air Purifier in your mind is one that’s inexpensive, yet strong and efficient, the Blueair Blue Pure 211 makes one compelling argument as the Best Large Room Air Purifier for indoor air cleaning. For starters, its price belies its performance. And given its Energy Star certification and low-cost filters, it takes very little to invest.

Why We Like It – Blueair Blue Pure 211

The Blueair Blue Pure 211 has great performance, low-cost replacement filters, and a one-button design for ease-of-use. And its price tag? Surprisingly affordable.

Pros
  • Great performance in large rooms
  • Filter replacements aren’t expensive
  • One button design
Cons
  • Lacks a HEPA filter
  • Lacks an air sensor

Power & Speed

The Blueair Blue Pure 211 has three different speeds to choose from, which is average for air purifiers of this nature. Crank it to its highest setting and you can get, at maximum, around 350 CFM. And as a bonus, it’s efficient with how it uses that power, only ever consuming energy at a rate of 30 to 60 watts. Its noise level is also low, with its highest setting never rising above a quiet, two-way conversation.

Efficiency

To put its power and speed into perspective, it handles rooms as large as 540 square feet with relative ease. It’s capable of swapping out air up to five times in a single hour, meaning you always have clean air quality every 12 minutes. On the other hand, the Alen BreatheSmart Classic Large Room Air Purifier covers 1100 square feet.

Versatility

The Blueair Blue Pure 211 has a 3-stage filtration system: pre filters, particle filters, then activated carbon filters. Its pre-filter captures large particles. Afterwards, the particle carbon filter, which combines the particle filter and activated carbon filter, takes care of 99% of allergen-causing contaminants like dust mites, pollen, and dust. Harmful gases are also targeted, thanks to the carbon and particle combo. Unfortunately, it lacks a HEPA filter, whereas the Coway Airmega 400 does.

Durability

This isn’t a lightweight air purifier, but it’s still compact. It weighs 22.4 lbs, making it hefty but durable. Its dimensions measure 13 x 13 x 20.4 inches, which means it has a larger base, but shorter for improved stability. Good luck trying to knock it over.

Value

We won’t knock the Blueair Blue Pure 211’s for its performance, but its lack of HEPA filter really hurts its value. Yes, it’s affordable and replacement filters are inexpensive, but it doesn’t change the fact that it’s missing smart features, like an air sensor. The Levoit Core 300 is half as effective in terms of coverage, but it too has a True HEPA filter, and it’s under $100.

Blueair Blue Pure 211 Wrap Up

If you want a reliable and affordable air purifier, it’s hard to at least consider the Blueair Blue Pure 211. It has the makings to be just that: a 3-stage filtration system for capturing allergens and gass, and good durability. Unfortunately, most air purifiers these days are almost always fitted with a True HEPA filter, but the Pure 211 isn’t.
