Whether praised or ill-spoken, the opinion on the effectiveness of air purifiers has remained a contested debate. However, we can all agree that the rapid tech revolution around air purifiers has been for the better. These silent but vital machines have continuously improved to eliminate smaller contaminants with incredibly high efficiencies.
Today, we shall look at some of the technologies embedded into the air purifiers as well as a review of the top 10 air purifiers we recommend to you. If you have been curious about how these purifiers manage to clean the air you breathe, check out some technologies used:
Thermodynamic Sterilization (TSS)
Uses the mode of incineration to burn microbes (fungi, viruses, bacteria, etc.) trapped from passing air, in capillaries heated to 2000C.
Ultraviolet Germicidal Irradiation (UVGI)
This technique uses a fan to force streams of air in front of a UV lamp which emits UV light, and therefore sterilizes the air.
For this system, air is also forced through a filter with specified pore sizes which will eliminate large contaminant particles, for instance, dust particles. A special class of these filters is the HEPA filter which is used to clean air entering a controlled environment (e.g. clean room, or even your guests’ room). They boast a cleaning efficiency of up to 99.97% of particles of 0.3 micrometers. Pretty impressive, huh?
Polarized-media Electronic Air Cleaners
These are a category utilizing an electronically active media to create a polarized electric field. Polarized substances will be attracted to this media as they pass by and will, therefore, be trapped. That’s only some of the technologies used by these wonderful devices. For a full list of these and more technologies being developed on air, purifiers follow this link (air purifying techniques). So which air purifier do you want? Don’t worry; we got your back. Check out these 10 of our most preferred models:
Top 10 Best Air Purifiers on the Market
1. HONEYWELL 17000-S

4. WINIX WAC5500
At a handling capacity of 350 square feet, this air purifier is not only ideal for a medium-sized office, but it is also suitable for individual rooms at home. The device incorporates modes technologies of Plasma wave, pre-filtrations using an activated carbon media as well as true HEPA filtration in its cleaning mechanism. With such a combination, you will be protected from pollen in the summer, floating flu viruses during the winter, and everything in between.
A smart helper
The WAC5500 gives you the option of choosing whether you want to work in manual or automatic modes. With the automatic setting, the device uses different sensors to pick up on the level of contaminants in the air (to classify on a scale of 1-5) and adjust the fan speed accordingly. With the manual mode, you’re free to switch between Low, Medium, High or Turbo setting for the fan speed.
What you also get is an automatic notification on when to replace your pre-filter. Usually, there will be a recommendation by the manufacturer (check your user manual), but this will vary depending on how hard the device works. Either way, you can rest easy, and the WAC5500 will notify you duly.

6. COWAY AP-1512HH
The 1512HH comes with both manual and automatic modes. Users can choose between the two modes, with either mode having a further specification for fan speed or air quality sensitivity.
The purifier has a rather tiny carbon footprint for its 267 cubic feet of air cleaned every minute. It is EPA Energy Star rated and will only consume about 7W when on low fan speed. It also has an innovative ECO Mode that will turn off the fan when contaminants in the air remain low for at least 30 minutes. So you can also breathe easy as it won’t be fighting for the first position on your electricity bill.
This air cleaner comes with three filters and a negative ionizer. The fiberglass pre-filter can be washed or vacuumed when clogged. It does a great job of trapping larger particles like dust and any hairs. Odor elimination is done by its carbon filters, right before the True HEPA filter takes over.
We recommend changing the HEPA yearly and the carbon filter every six months. Otherwise, there’s a LED indicator to let you know when to replace the filters.
