2019 Airfree Onix 3000 Filterless Air Purifier Review: Look ma, no filter!

Black coated Airfree Onix 3000 is the "NEW" filterless air purifier. When we said new, it is still the good ol' Thermodynamic TSS Technology that is used across Airfree lineup. So compared with other permanent air purifiers that do not use a filter, how effective is Onix? What about its purifying applicable radius? Will it stand tall from other conventional air purifiers?

Airfree Onix 3000 review

Sterilization method that is super effective against microorganisms like mold and pollen.
The TSS ceramic core does not require any maintenance or cleaning.
No recurring cost as the air purifier does not use any filter at all.
Fits anywhere with its compact and lightweight body.
Stress-free light can be adjusted on brightness intensity.
Absolute silent operation thus it will work exceptionally well in the bedroom.
2 years warranty that covers all manufacturer defects.

Purification works on a gradual basis that could take days to clean up a room.
Less effective on dust, smoke and odor compared with conventional filter-type.
Plain vanilla unit with no add-on features.

Dimension

8.4 x 10.4 x 8.4 in

(21.3 x 26.4 x 21.3 cm)

Weight

3.3 lb (1.5 kg)

Like its award-winning design siblings, Airfree Onix 3000 derives straight from it. It has a very compact and lightweight body at 8.4 x 10.4 x 8.4 in and 3.3 lb weight. There are 2 side shells that I suppose it can assist you with the carrying? In any case, you will definitely have no problem carrying and placing it around the house. Air inlet is at the bottom air convection while air outlet is at top. Overall, the solid build quality would have no issue serving you for many years down the road.

Let’s talk about the one and only control. The adjustable anti-stress night light. Right between the 2 side shells, there is a light intensity touch sensor. You can easily adjust the night light brightness or turn it off during day time. Other than the anti-stress light, this air purifier is pretty much a plug and play unit.

Lastly, Let’s talk about passive features. All Airfree air purifiers are CARB certified for ozone-free. There is also thermal fuse, tilt sensor, varistor, current limiting fuse and Thermistor safety sensors.

Purifying coverage

650 sq. ft. (60 m²)

Fanspeed

Like Iris 3000, Airfree Onix 3000 has a wide 650 sq. ft. purifying coverage. Great but the whole the sterilization process might take a while. The air purifier must be in continuous operation in order to be truly effective. You will only see the improvement gradually which could take up to 30 days.

What’s inside count

Patented Thermodynamic TSS Technology

^ Airfree Onix 3000 filters/ technologies/ lifespan

Works similarly to boiling water where microorganisms are destroyed at high temperature. First, the inflow contaminants will be trap inside the TSS ceramic core. The mini-ducts inside the core would begin heating the air over 400°F (200°C). At this point, up to 99.99% of the contaminants are eliminated on the spot and left to cool down inside the machine. The clean air would then be release out without affecting the room temperature. The entire sterilization process is safe, no emissions, ions or new particles generated. In fact, Airfree Onix 3000 help reduces ozone by 26% as tested in Sweden's laboratories.

Thermodynamic TSS Technology is brilliant taking on allergens and microorganisms. This includes mold, pollen dust mites, virus, fungus, bacteria, and pet dander. On fumes, smokes, and tobacco smell, Airfree Onix 3000 can reduce the density but not at a superb level.

Keep it down

Noise level

SILENT

Power consumption

52 W

Complete silent operation is one of the main highlight in this air purifier. The whole sterilization does not rely on a fan or any motor. Ideal for bedroom where you could leave the machine on 24x7. 52W Power consumption is not the lowest in Airfree lineup but is still on a low tier. The good thing is Onix 3000 will shut down its ceramic core and enter into energy-saving mode once it reaches a certain temperature.

^ Replacement filters/ estimated cost

We all know filter replacement is usually an air purifier Achilles heel. Airfree Onix 3000 base price is far from cheap, but the forever no recurring cost is what sweetens the deal. Plus, it is environmental-friendly because there is no filters or UV light lamp to toss away. Give yourself a big thumbs up for being an eco-warrior!

Amazon is the best place to get Airfree Onix 3000 as the availability is rather limited. You may or may not enjoy the free shipping, but 30-days no questions asked return policy is standard here. Best Buy and Walmart do carry the model, but again, availability trouble pops up. Airfree official site does not have a web store so you forget about that.

Airfree Onix 3000 VS the challengers

Airfree Iris 3000

Identical model inside and out. The only difference is Iris 3000 comes with adjustable multi-color stress-free light. Expect little bumps on the pricing.

Airfree P2000

Older, non-black version that is cheaper in price tag. You will lose out on a lower purifying coverage (550 sq. ft.).

Honeywell AirGenius 5 HFD320

Let's try something different. It uses a permanent ifD filter that traps particles rather than eliminating them. Pre-filter can be upgraded with a better odor-reducing filter.

Final thoughts on Airfree Onix 3000

Love it or hate it. That's what most people thought of Airfree Onix 3000. 71% of the reviewers are happy with the outcome. They see their allergies disappear, along with all the symptoms. The frequency of mold, pollen from popping out also significantly reduced. The rather high 21% haters did not see with us. They feel the air purifier does nothing in improving their current allergy state. Some even think the whole thing is just a scam that we beg to defer. Since we tested the unit, we are on the believer side but in the end, it's up to you to decide which side to stand on.
