The air inside is as polluted as the air outside. Air purifiers remove particulates from the air that are harmful to human health. These particles can include pollen, dust, pet dander, and other harmful particles.
Increasing emissions of CO2 in the air is making our atmosphere harmful to breathe. This air is trapped in our homes that unknowingly affects our respiratory system. According to the World Health Organization, indoor air is among the top environmental health risks. An air purifier is important for those who suffer from diseases such as eczema and asthma.
If you are looking to buy an air purifier but don’t know where to start, read our blog. We will guide you through and help you in asking the most important questions before purchasing one.
Why Do You Need An Air Purifier?
Several air purifiers are available in the market according to the needs of the buyer. Some people want an air purifier just to purify the air, but air purifiers come with different purposes, such as:
- For allergies, you may need an allergy relief air purifier
- If you own pets, you would need a pet air purifier
- Smoke air purifiers will clean out smoke and fireplace soot
- Multiple Chemical Sensitive (MCS) purifiers for those sensitive to chemicals
Even if you don’t suffer from any allergies, the presence of harmful particles can affect you. They can lower your immunity and make it hard for you to breathe. Knowing which type of air purifier to buy will narrow down your options and ease your decision.
What Matches The Size Of Your Room?
Air purifiers come in different sizes and speeds. Know the size of your room by multiplying its length with the width. Different sizes of air purifiers are suitable for rooms of different square feet areas. For example:
- Small ones are suitable for a room of about 300 square feet
- Medium purifiers are suitable for a 300-700 square foot area
- Large air purifiers are suitable for 700-1900 square foot rooms
Apart from this, air purifiers have a unique Air Change per Hour rate (ACH). It is the number of times an air purifier cleans the air in an hour. An air purifier that cleans the air at least 4 times in an hour is a good one.
Therefore, a model with a coverage area 500 square feet with 3 ACH will clean air 3 times in an hour.
