What Features Make Plug in Air Purifier the Best; Buying Guide

A plethora of air purifiers is increasing daily, leaving people confused about which is the best one. There is no fixed definition of the perfect one, but a few essential features play a significant role in the working. Every air purifier is best if it fulfills your requirement. These are essential features that you should take into consideration.

1.     Filtration

For plug-in air purifiers, go for at least 3-stage filtration systems. This will include genuine HEPA filters for the elimination of small particles, pre-filters for large particles, and activated carbon filters for pleasant air.

Collectively, these filters provide a strong defense against harmful particles.

They can trap particles as small as 0.3 microns and filter 99.95% of contaminants.

The built-in ionizers and UV-C light can provide even a robust filtration system.

2.     Coverage

Some plug-in air purifiers are designed to cover a large area, whereas some can clean air in the range of 100 square feet. In order to get the ideal unit for your room, you need to measure the room in square feet then check the coverage area capacity of the unit. If the device matches the area of your room, then you can expect results.

3.     CDAR rating

The clean air delivery rate or CDAR is a unit created to measure how effective an air purifier is in eliminating contaminants from the air per minute.

It is generally measured in cubic feet. The will be the CDAR rate, the more effective it will eradicate contaminants. If you are willing to keep your air free from the weed smell, ensure to get the unit with a high CADR rating.

4.     Noise

Noise is not a primary feature that many people might consider, but you will regret it later when you will have to sleep with engine sound.

It is because close places can make the sound echo and create irritating sound. Similarly, some devices have decibel ratings.

Therefore, look for a unit with a minimum decibel rating. The considerable noise level is 30, but below 60dB is also acceptable at high speed.

5.     Quality and durability

A Plug-in air purifier is not something you would like to replace daily. Therefore, take the unit that is well-known and can give you a long run.

With durability, high-quality functioning air purifiers can make you and your environment healthy as they do not produce harmful gasses like ozone. Ensuring the internal as well as external air of the house is a key to a healthy life.

However, check the unit’s guarantee as the machine can betray you anytime. Choose the unit with at least one year warranty for the safe side.
