Best Air Purifiers

Best Air Purifiers

Are the air purifiers necessary? We don’t think so!

But in some cases they are required. For example, areas with poor air quality, densely populated office areas, or indoors with poor air circulation.

Energy efficient windows and doors are good at keeping pollutants out of your home, but they also trap in a lot of bad stuff.

According to the Environmental Protection Agency(About EPA), the concentration of some pollutants is often two to five times higher indoors than outdoors.

A good air purifier can reduce some pollutants and help you breathe more easily.

When we evaluate air purifiers, we mainly test their price, quality and efficiency (how much bacteria they claim to absorb).

In the end, we got this list of Top5 lists.

5 Best Air Purifiers 2019:

1. Coway AP-1512HH Mighty

Coway AP-1512HH Mighty

One of the keys to Coway’s performance is its manufacturing quality, especially the close cooperation of its pre-filter and HEPA filter.

The pre-filter traps large particles, such as pet hair and fluff, which would otherwise block the HEPA filter and reduce its ability to trap fine particles.

At the same time, HEPA filters can be tightly mounted in Coway’s frame and tightly sealed in a plastic housing.

This prevents air from bypassing the edge filter and ensures that almost all air drawn from the machine is HEPA filtered, a design that is likely to contribute to Coway’s excellent performance.

In addition, Coway has many other features that make it easy to use, which is very important for devices that usually run 24 hours a day and are located in the bedroom, game room or living room.

Finally, Coway can maintain its excellent performance for a long time: we have repeatedly measured its performance for 2 consecutive years, and the effect is the same every time the air is purified.

Pros /Cons
  • Outstanding manufacturing quality
  • HEPA filter
  • Small footprint
  • Long-term stable performance
  • The ceiling light cannot be turned off

Can Air Purifiers Help?

The best way to improve indoor air quality is to remove sources of pollution and use clean outdoor air for ventilation.

Air purifiers, also known as air filters, are designed to filter the air in a single room, not the entire room like a HVAC system.

Although they do help reduce indoor pollution, their effects are limited.

Types of Air Purifiers

There are several technologies for air purifiers to address indoor pollution. Some products do better than others. But some products are actually harmful to your health.

  • Mechanical filters: This is the type we tested. They used fans to force air through a dense network of fine fibers to trap particles. Can remove larger particles, including dust, pollen, and some mold spores suspended in the air (please pay attention to whether it is a true HEPA filter when buying).
  • Activated carbon filters: Unlike mechanical filters, adsorbent filters use activated carbon to adsorb some odor molecules in the air. They may also handle some gases, but they are not particularly effective against formaldehyde, ammonia or nitrogen oxides.
  • Ozone generators: These machines produce ozone, a molecule that can react with certain pollutants to change its chemical composition. This can lead to dangerous indoor air quality and we do not recommend them.
  • Photocatalytic oxidation: PCO uses ultraviolet radiation and photocatalysts, such as titanium dioxide, to generate hydroxyl radicals that oxidize gaseous pollutants. Depending on the pollutant, this reaction sometimes produces harmful by-products such as ozone, formaldehyde, nitrogen dioxide, and carbon monoxide.
