Replacing the Filters

How do air filters work?

Air filters clean the air by passing it through various filters that remove particles like mold, dust, pollen, pet dander and more. They act as a screen to capture particles as air flows through them.

Do air purifiers help with mold?

Using an air purifier with a true HEPA filter can help with removing mold spores from the air. Whether the spores are coming from an existing problem inside the home or from the outdoors, if they are in the air, the air purifier can filter them out before they have a chance to settle onto surfaces.

Do air purifiers help with allergies?

An air purifier that uses a true HEPA filter will trap common allergens such as mold spores, dust, pollen and pet dander. Since some allergens can also come from outdoors, such as pollen, anything that is brought in from the outdoors can easily be kicked up and become airborne then trapped in the air purifier filters.

Do air purifiers help with dust?

While no purifier will get rid of all the dust in your home, they can certainly help with dust. A combination of regular cleaning, limiting the dust that you allow into your home, and an air purifier with a True HEPA filter will make your home as dust-free as possible.

What is an air purifier?

An air purifier or air cleaner is a device which removes contaminants from the air in a room to improve indoor air quality. It’s used to limit the spread of harmful allergens and to prevent asthma or allergy problems related to air quality.

Where to place an air purifier?

Typically you want to place an air purifier in places where air flow travels the most. By placing an air purifier 3-5 feet off the ground, you are able to capture both the horizontal and vertical air movement. Entry points such as hallways, doorways, or near windows are good places to place an air purifier. Avoid putting in places where there is poor air flow, such as a corner, on the floor, or in between obstacles.

Are air purifiers safe?

True HEPA filter-based air purifiers produce no harmful effects and are generally good for your health as long as they are properly maintained. They remove harmful particles and allergens from the air, leaving only fresh air behind. Ozone generating air purifiers are a poor choice and are potentially harmful to your health.

How many air purifiers do I need?

Each VEVA 8000 air purifier covers 325 sq. ft, perfect for most rooms in a home or office space. The VEVA ProHEPA 9000 on the other hand is well suited for larger rooms, capable of keeping the air clean for 600+ sq. ft if you need to cover a wider space.
