Let’s jump straight to the part that differentiates Iris 3000 from Onix 3000. The former comes with Multi-Color night light rather than a fixed blue light. You can choose a favorite color or adjust the brightness level through the control. Other than that, operate the air purifier is dead easy. Just plug and play and off you go.

Filters And Performance

Airfree Iris 3000 patented Thermodynamic TSS technology works in a similar fashion as boiling water. When particles flow through the air convection, the mini-ducts will begin the heating process. This will go on for a couple of minutes until it reaches a boiling point of 400°F (200°C). The increased temperature will kill off any microorganisms that are trapped within. After that, the air will be left cool off in the air purifier before release back out in the wild. The whole process is safe, eco-friendly, release no emission or ion. There is no maintenance needed as no filter is used during the entire purification. In fact, research in Sweden also shown that Airfree Iris 3000 can help reduces ozone by 26%.

Airfree Iris 3000 price is on the higher side even in its own lineup. Onix 3000 would be the better buy if you can let go of the multi-color night light. What you can save up is the filter cost as there is absolutely none. This is the best part of owning a filterless air purifier. By opting for a filter-free air cleaning machine, you are not wasting carbon sheets and unrecyclable parts that is detrimental to our environment.
Forget about Airfree website as they don't have a web store. Retailers like Best Buy, Walmart may carry the brand but with limited availability (made in Portugal). Your best bet is Amazon as of last we checked, they are still selling at a discounted price with 30 days return policy if you are not satisfied. Free shipping is not included but things might change with deals regularly throw in. Do look out for other Airfree models for price comparison as they are essentially the same product. Otherwise, consider the filterless air purifiers below.
