The starters

Airfree Lotus dimension


7.7 x 13 x 7.7 in

(19.6 x 33 x 19.6 cm)

Airfree Lotus weight

Airfree Lotus design is unique in many ways. the 7.7 x 13 x 7.7 dimension is unlike most Airfree models even though weight is consistent at 3.3 lb. Inspired by the mysticism of Lotus flower, the color light that will beam up like flower petals. Great for home decor or as a night light for children. Air inlet is located at the bottom air convection while air outlet is at top. Carrying around the air purifier is as easy as carrying a laptop thus no issue packing it for travel.

Like all Airfree air purifier, there is only 1 control and is for the adjustable night light. You can adjust the light intensity or color via the touch control sensor. Other than that, it is the ultimate form of plug and play model.

With no other function to talk about, let’s quickly recap on its features. The air purifier is CARB certified ozone-free with 2 years warranty. It comes with passive safety tech to prevent any short-circuit. This includes Thermistor safety sensors, thermal fuse, tilt sensor, varistor, and current limiting.

Airfree Lotus coverage

Purifying coverage

650 sq. ft. (60 m2)

Airfree Lotus fanspeed

Airfree Lotus Filterless air purifier has a wide 650 sq. ft. purifying coverage same as Onix 3000 and Iris 3000. It uses the same TSS sterilization method that is slow but effective. Ideal of bedroom, living hall, basement, office or even kindergarten. The air purifier is required to turn on 24×7 and placed at a fix location for optimal performance. One should expect up to 30 days purification for a completely clean air overhaul.

What’s inside count

Think about it as a bottle sterilizer but at a higher output. Airfree Lotus patented Thermodynamic TSS technology works in a similar fashion. The inner mini-ducts heats the air over 400°F (200°C), killing 99.99% of the allergens and microorganism in the process. Finally, the air will be cool off inside the machine so only cool, clean air will be flown back out. The whole purification is eco-friendly, emits no ion, and ozone (reduces ozone in fact).

Thermodynamic TSS Technology is super effective against microorganisms including mildew, mold, and pollen. Same goes with allergens like bacteria and viruses that are normally hard to capture. Smoke and odor is not its strong suit but rest assured, it can still reduce its presence in the air.

Keep it down

Airfree Lotus noise level
Airfree Lotus power consumption

Without the humming noise from the motor fan, Airfree Lotus is 100%, completely silent. Great for all places that would not disturb your daily activity, TV or sleep time at all. Power consumption is low (52 W) that is further enhanced with the auto energy saving mode. The air purifier will shut off its ceramic core once it reaches a temperature peak point.

At what cost

Airfree Lotus annual filter replacement cost
^ Replacement filters/ estimated cost

Let’s keep this part short. Airfree Lotus is expensive but in long-run it would’t be because it is an amazing filterless air purifier. There will never be any annual filter replacement cost. You are also saving the planet by not contributing to any filter, UV lamp or carbon sheet waste.

Is not easy to find Airfree Lotus other than Amazon. If is indeed available, you can even get it at a much cheaper price than the retailers like Best Buy or Walmart. There is no official web store here but you can look up for nearby distributor from Airfree’s website. If you want to save up more on the initial cost, consider the 3 alternatives below.

Airfree Lotus VS the challengers

Airfree Iris 3000

Airfree Iris 3000

Cheaper price with the exact same purifying technology, coverage and airflow performance. You do have to give up on the opening flower petal design.

Airfree Onix 3000

Airfree Onix 3000

Even cheaper with the same performance offering and TSS technology. Very identical to Onix 3000 but have to do with a fix “anti-stress” night light.

Honeywell AirGenius5 HFD320

Honeywell AirGenius 5 HFD320

Technically a hybrid air purifier with a permanent filter that can be reused over and over again. If you want a more conventional purifying method that traps particles rather then boiling them, this is it.

Final thoughts on Airfree Lotus

The only air purifier we reviewed with 100% positive feedback! Before you get overly excited, this is out of the 9 (YES 9) reviewers that gave it a 4-5 stars rating. They like the build quality (made in Europe), the “fun” night light, and completely silent operation. Perhaps what makes them really happy is the drop in allergy symptoms without the hassle filter replacing. Bring to a conclusion, Airfree Lotus is exactly what we would expect from it. No more, no less. If you are OK with the slow purifying time frame, this would do well.
