BlueAir ECO10 Air Purifier Review

BlueAir ECO10 air purifierI decided to review this air purifier due to its high energy star ratings and a good 3-stage filtration system.

I was also interested in the HEPASilent technology, which promises almost silent operation while picking up even the smallest contaminants. Even though this air purifier is designed for rather small areas, the manufacturer claims excellent results.

I didn’t appreciate the design of the purifier. However, BlueAir is a respectable manufacturer, so I decided to give it the benefit of the doubt. I also liked the limited lifetime warranty so it seemed this unit is worth checking out. Let’s take a closer look.

Filtration System

This air purifier comes with a 3-stage filtration system.

Pre-filter – This permanent pre-filter keeps the large particles from going further inside the air purifier, extending the lifespan of other filters. It’s located on top of the air purifier and can be vacuumed on a regular basis. I would recommend doing it at least once a month. No replacement necessary.

HEPASilent Particle Filter – This filter takes care of the majority of contaminants since it can catch 99.97% of particles 0.3 microns in size. This high-quality filter does an excellent job keeping your home clean. It needs to be replaced at least once a year. However, you can delay replacement if you are not using the air purifier on a regular basis. The price tag for this filter is about $100.

Ionizer – The air purifier has built-in ionizer brushes that make it easier for the filters to catch contaminants. The ionizer works inside the unit and doesn’t produce any ozone. You can’t turn the ionizer off. It’s an integral part of the HEPASilent technology.

Even though the rest of BlueAir models come with a carbon filter, this one doesn’t, for some reason. Smokestop™ Filter Kits are available for other models but not for this one. The HEPA filter kit seems to have some activated carbon sheets included.

Overall, the particle filter kit includes three filters, which do a very good job. The technology involves electrostatic and mechanical filtration.

The yearly maintenance of this unit will cost you $100, which is fair.


BlueAir ECO10 - HEPASilent Filtration



BlueAir ECO10 - designUsually, BlueAir does a great job with the design of its units. But this time something must have gone wrong. The air purifier is made of galvanized steel and supposed to be very durable. In reality, the case appears to be rather flimsy. When you open it up to replace the filters, it seems as if it may not close back. The construction lacks durability and reminds you of an old air purifier model that should have been pensioned off years ago.

Coupled with high-quality HEPAsilent technology, it looks a bit strange. Even though the air purifier services a rather small area, it’s big and heavy. It weighs 35 pounds. The sizes are 20 x 26 x 13 inches. The case is equipped with built-in caster wheels, making the unit easy to transport. However, if you need to move it from one floor to another, you’ll be breaking a sweat.

The model doesn’t have an LCD screen. It has a knob for fan speed adjustment on the side. There aren’t any filer replacement indication lights.

The unit needs to be placed at least 4 inches away from the walls or any other furniture in order not to interfere with the air circulation.

Smart Options and Sensors

Unfortunately, this particular air purifier doesn’t feature any smart options. It doesn’t measure the air quality or tell you when you need to replace the filter. It lacks a remote control. In the era of smart homes and highly sophisticated gadgets, a one-knob air purifier seems like a creature from another planet.

Of course, there are certain benefits that come with a lack of sensors and smart options. The unit is easy to use. You just plug it in and set the fan speed. Meanwhile, you don’t have to worry about sensors breaking down.

Noise Levels

This is the best part of this air purifier and for some people, it may neutralize all the other problems. This is a very quiet unit. Even at the highest fan setting, it’s not loud. The fan has two speeds:

  • High speed – 49 dB
  • Low speed – 40 dB

At the high speed, the noise level is similar to a very quiet conversation. At the low speed, it’s almost inaudible. Accordingly, it’s a good choice for light sleepers, who prefer using the air purifier in their bedrooms. In fact, it produces a white noise, which can help many people fall asleep.

Energy Efficiency

Another big advantage of this air purifier is its energy efficiency. This model uses only 10 watts of energy at its highest speed. The low speed needs about 7 watts. Compared to other air purifiers in the same price category, the energy efficiency of this one is impressive. It can help you save money on energy bills.

Coverage Area

The manufacturer claims that the coverage area of this air purifier is 220 square feet. This is good for a mid-size room. Let’s look at the CADR ratings to double check.

  • Smoke – 190
  • Dust – 195
  • Pollen – 200

By making the calculations using our favorite formula (CADR x 1.5), we get 285 square feet. Why such a big difference? It probably has to do with the number of air changes. In the 220 square foot room, the air purifier makes about 5 air changes per hour, which is a very good indication.

It can service a large room too, but the number of air changes would decrease. Still, I think you can safely use this air purifier in a room up to 300 square feet in size.



BlueAir offers a limited lifetime mechanical warranty on this product. If you take care of the unit as shown in the manual and change filters at least once every 12 months, you can take advantage of the warranty, in case your unit is malfunctioning. I appreciate this long-term warranty since it speaks highly of the product’s integrity.

The air purifier comes with a 30-day satisfaction guarantee. You can return the item within 30 days of purchase with no questions asked.

BlueAir ECO10 Air Purifier Review Conclusion

I would say that this model is pretty average. I would recommend it to people who don’t care for the smart options and aren’t overly critical about the air purifier’s design. This model does a good job clearing the air and catching mold spores, pet dander, allergens, etc. However, there is a variety of feature-packed air purifiers for the same price available on the market today. I think you would do better to look at either the winix 5300-2. or the coway ap-1512hh which both have smart options and can clean more air in a faster time. Or if you’re really sold on blueair products, then I highly suggest you take a look at the blue pure 211 which is possibly one of the best air purifiers money can buy right now.
