2023 review update: Idylis air purifiers are not available anymore and discontinued. It’s not a problem since there are many air purifiers that are even better when compared to any Idylis air cleaner. They are either have better filtration system like it is the case with the Air Health Skye or are cheaper and have lower maintenance costs.

Here are my top picks of best alternatives to Idylis air purifiers.

Double HEPA and Carbon filters on Idylis 5-speed air purifier do a good job cleaning air from airborne particles, but when it comes to viruses and bacteria additional cleaning is required. That’s where the Air Health Skye comes in handy.

This air purifier features PCO-cell and UV-light. In combination, they clean air from viruses, bacteria, VOCs (volatile organic compounds), chemicals and fungi into a harmless water vapor. I explain more in my review here.

In total, Air Health Sky features 5-stage air cleaning:

  1. Pre-filter (missing in Idylis): traps large particles, extends lifespan of internal filters;
  2. HEPA H13 air filter with 99.97% efficiency of capturing particles as small as 0.3 micron;
  3. Carbon Filter to remove various odors;
  4. PCO-cell (missing in Idylis);
  5. UV-light (missing in Idylis) to deactivate viruses. In a combination with the PCO-cell destroys fungi, bacteria, VOCs.

In in all, this 5-stage air cleaning technology makes sure the air inside a room will be clean of all possible chemicals, particles and gases whereas Idylis targets only odor and physical particles.

The Auto mode uses data of 3 particles sensors, VOC sensor and Inorganic gases sensor meaning that it will automatically adjust the air purifier speed precisely in accordance to the air quality inside.

The Air Health Skye is AHAM-Verifide, meaning that it was independently tested and proved to clean air from smoke, dust and pollen. It can cover rooms up to 550 sq. ft. with 4 air changes per hour. Check this article for more information on ACH.

4 air changes per hour is bare minimum that people with any breathing conditions (i.e. asthma) should aim for. People without any such conditions can use air purifiers that deliver at least 2 ACH.

This air cleaner also features 10 speed settings for more delicate control over the fan speed, is super quiet at night and has an app support.

In terms of power consumption Air Health Skye is also a winner. It consumes twice less energy, so in a long run it will save up some money that otherwise would’ve been spent on the electricity bills.

All in all, the Air Health Skye is the ultimate solution for people who looking for an air purifier that clean air from all possible pollutants in rooms larger than 400 sq. ft.

Coway has 2 major advantages over the Idylis:

  • Higher CADR ratings for dust, pollen and smoke. It means the Airmega AP-1512HH cleans more air in 1 hour which is a great news for allergic people since they require more air changes per hour than the average Joe.
  • It includes pre-filter in the filtration system to trap large particles like hair, dander and so on.

The Coway Airmega AP-1512HH also features an ionizer. It helps the HEPA filter to capture airborne pollutants and freshens the air. The ionizer can be turned off if you aren’t tolerant to ozone.

Idylis 3-Speed 232-sq. ft. HEPA Air Purifier was not bad, but now there are several great alternatives to it, and Levoit Core 300s is the best among them.

Compared to the Idylis, the Core 300s employs additional pre-filter for the better air filtration and cleaning. It also protects the other filters (HEPA and Carbon) from getting dirty too fast, resulting in lower operating cost.

In terms of room coverage and CADR they are almost identical, the Idylis AC-2123 is slightly ahead. But overall both air purifiers clean air more or less the same.

When it comes to the additional features, the Core 300s is miles ahead of the Idylis. See for yourself:

  • Auto mode: the air purifier detects air quality in the room and adjusts the speed accordingly;
  • Sleep mode is very convenient if the air purifier is used 24/7 in a bedroom, as it turns off the display and run very quietly at night;
  • Extremely low power consumption at only 26 Watts per hour;
  • App support: it allows to control the Levoit Core 300s from anywhere in the home. The app also features PM 2.5 dust air quality sensor;
  • Display lock to prevent settings changes.

Overall, the Levoit Core 600s is a great alternative for the Idylis AC-2123 for a lower cost.
