How many air purifiers do I need

Air Purifier is good for our health. PM2.5:the tiny particles, and other particles, such as pet hair, dust, etc, could cause lung damage, cognitive impairment, allergies, and shortened lifespan. The best way to keep your home fresh is to use a true HEPA air purifier. But how many air purifiers do I need to keep our family safe? Do I need multiple air purifiers for my apartment? In this article, we will find the factors for these questions.

How Many Air Purifiers Do I Need?

Air purifiers with HEPA filters rely on air circulation so that they can operate properly. This means: although the air purifier will affect the area around the principal cleaning zone, such as the hallway or foyer, the cleanest air is just the place where the air purifier is set.

A house with 2 or 3 floors, air purifiers cannot pass through walls, corners, hallways, or even downstairs to purify the air in a living or workspace. This means that home with multiple rooms often require multiple air purifiers. It also means that indoor spaces with open floor plans may require fewer purifiers.

Depends on: How Big is Your House

Room size is the key to determining how many air purifiers I will need. To determine which air purifier I'll need for each room, it's important to consider the CADR.

CADR, CADR stands for Clean Air Delivery Rate. CADR means the amount of air filtered in one hour for 3 specific pollutants (smoke, pollen, and dust) per unit CFM. The higher the CADR rating, the more air the air purifier can clean per hour.

It is unnecessary to buy a too-big air purifier for your single room, because it costs too much both money and resources. On the other hand, a too-small air purifier will affect your indoor air quality. By doing a few simple calculations, you will be able to find the ideal size air purifier for your room.

If you feel it is difficult to calculate those parameter, you can visit some online calculators to estimate the CADR required for each room, for example, reviewsofairepurifier.com

By comparing the result with the Specification of Product CADR, you will more clearly know how many air purifiers you need for home.

Depends on: Where to Place the Air Purifier in Your House

The efficacy of air purifiers depends on where they are placed. Although air purifiers can take in the air everywhere in the room, they work well only when they get plenty of air and good airflow. The more air is available, the faster it will purify. DO NOT place the air purifier in the corner.

Don’t forget the Vertical direction: The difference in temperature in the vertical area lets the airflow in the vertical direction; the hot air will flow up to the ceiling.

Placing the air purifier about 1 meter above the ground allows the air purifier to benefit from the flow of air in both directions.

Avoid the humidity, High humidity means that the air is heavier. The air purifier requires more energy to effectively ventilate; on the other hand, the humid air will reduce the filter's (especially the HEPA filter) performance.

Depends on: Pollutants in the Room

Pollutants can enter your home both through human activity and through infiltrating outdoor air. Activities such as cooking, heating, cleaning, painting, and using scented products can all contribute to pollution. Rooms with pets are also likely to contain more pollution due to pet dander and pet hair. Kitchens, basements, and bedrooms are all places that typically contain the highest levels of pollution.

Depends on: The Time You Spend at Home

If the kitchen and the living room seem to be the rooms where we spend the most time at home, it is actually in the bedroom where we spend the most time. This is explained by the fact that sleep occupies a third of our lives.

Keeping the air in your bedroom clean is particularly important, as the quality of our sleep is critical to our health. Insomnia can affect your work, your studies, and your risk of injury. People with sleep disorders are more vulnerable to a myriad of health problems, including heart disease, high blood pressure, stroke, diabetes, and obesity.

Besides all pollutants that can affect your sleep, some of them are more harmful than others. Allergens such as dust, and pet dander can disrupt periods of deep breathing that are essential for healthy sleep.

Volatile organic compounds (VOCs), which are released by many common products, can also cause sleep problems. Breathing in VOCs while sleeping affects the central nervous system and can lead to breathing problems like sleep apnea.
