Air purifiers provide a cleaner and fresher indoor and also improve the ease of breathing. They do this by eliminating pollutants, including VOCs and other particulate matter in the air. These pollutants are health-damaging and can cause acute to long-term ailments. This is why you need to know what to pay attention to while buying an air purifier?

This air purifier buying guide contains some helpful tips on how to choose an air purifier and what to look for in one. We will discuss the essential factors to consider when buying an air purifier.

Considering “why do you need an air purifier?

The first step in getting a good air purifier is to decipher why one is necessary. Sometimes, the reason for buying an air purifier may determine the specification of the one that is needed. Generally, air cleaners are used to remove pollutants in indoor air that may be harmful when inhaled. Polluted indoor air may be full of gases from cleaning products, dust, mites, and allergens. So, you can get air purifiers to help with specific indoor air-related needs.

Air purifiers help with:

All these reasons help answer the question of ‘what are air purifiers used for?’. We hope that is clear!

AIR8 air purifiers

It also gets rid of allergens, dust, and viruses (including active viruses like Coronavirus). It helps provide cleaner indoor air with the aid of efficient medical-grade technology.

What type of air purifier do you need?

The available variety can make shopping overwhelming. But to help when making a perfect decision, it is best to understand the different types of air purifiers available and their specific function and filtration technology differences.

High-Efficiency Particulate Air (HEPA) Filtration

This type of air filtration technology is considered the best type for air purification. It is very efficient and can remove different types of pollutants from the air, including bacteria, viruses, harmful gases, pollen, dust, and some VOCs.  HEPA filters are capable of removing 99.97% of malicious particles from the air, making any indoor environment safe.

Activated Carbon Filtration

These filters make use of sorbent-type filters that absorb molecules that cause odor in the air. It consists of activated carbon with many tiny pores, which can trap gases, fumes, smoke, and odor from the air. They are only able to trap gases that cause a smell and do not tackle the particulate matter.

Ionic Filtration

This has an interesting mechanism of operation. It eliminates contaminants by releasing charged ions into the air. These charges ions are bonded to the air contaminants and destroy them. The destroyed contaminants fall onto the ground and other surfaces.

It is efficient in getting rid of microscopic to ultra-fine particles in the air. They are less expensive and don’t have a fan which makes them noiseless.

What ACH and CADR ratings are best?

When estimating what to look out for in an air purifier, the ACH and CADR rating must not be left out. When purchasing an air purifier, you’re most likely to come across these specifications. They are essential and need attentiveness to understand.

ACH meaning Air Changes per Hour

ACH ratings are overlooked mainly by buyers because they do not understand them. However, it is an important feature that can tell a person more about the efficiency of the product they are about to buy. The ACH rating describes how often the air purifier can clean the air in the room every hour. The ratings may be indicated as 4x, 5x, or even 6x. This tells the buyer that the air purifier can exchange the air in the room.

A 6x rating means that it can recycle air six times in an hour. The higher the rating, the more efficient the appliance will be at cleaning indoor air. ACH is calculated on the basis of the size and height of the room.

CADR meaning Clean Air Delivery Rate

This is another standard used to compare the efficiency of the device. The CADR rating guarantees that if the air purifier is said to clean up a particular space or pollutant, it is tested and certified to be true. CADR measures three air pollutants; smoke, pollen, and dust.The higher the rating on the product, the more efficient it will be at eliminating the three different pollutants.  When you want to buy an air purifier, compare different ratings on different brands. This will provide a clue on which is better at eliminating certain pollutants.

What size should you get?
