Frequently asked questions - Air Purifiers

Do air purifiers work?

Yes, air purifiers can be effective in improving indoor air quality by removing harmful particles and pollutants from the air.

Air purifiers work by using a combination of filters and technologies, such as HEPA (High Efficiency Particulate Air) filters, activated carbon, and other technologies to capture and eliminate airborne particles, such as dust, allergens, mold spores, pet dander, and even bacteria and viruses. ¹⁰

Do air purifiers help with dust?

Yes, air purifiers can help with dust by capturing and removing airborne particles from the air.

Dust and other small particles may contribute to respiratory problems and allergies. High Efficiency Particulate Air (HEPA) filters are especially effective at capturing tiny particles like dust, pollen, and pet dander. ¹⁰

Are air purifiers worth it?

Whether an air purifier is worth it or not depends on your specific needs and circumstances.

Air purifiers can be beneficial for people who want to improve indoor air quality in general. They can help to remove harmful particles and pollutants from the air, including dust, allergens, pet dander, and some are proven to filter bacteria, viruses, and mold spores. ¹⁰

What does an air purifier do?

An air purifier is a device that cleans the air in a room or a building by removing potentially harmful particles and pollutants, such as dust, pollen, pet dander, and other airborne contaminants. ¹⁰

It works by drawing air through a filter, which traps these particles and releases cleaner air back into the room.

Some of the benefits of using an air purifier include:

  1. Improved indoor air quality: An air purifier can remove harmful particles and pollutants from the air, leading to cleaner air indoors.
  2. Reduced odors: Some air purifiers can help to remove unpleasant odors from the air, such as those caused by cooking, pets, or smoking.
Do air purifiers help with allergies?

Yes, air purifiers can help to remove allergens such as pollen, dust, and pet dander from the air.

Air purifiers work by drawing in air and passing it through a filter, which traps pollutants and allergens. Some air purifiers are specifically designed with HEPA (High-Efficiency Particulate Air) filters, which have a high removal percentage for very small particles, including many common allergens.

Studies have shown that using an air purifier with a HEPA filter can help to reduce the concentration of airborne allergens in indoor spaces.

Do air purifiers help with mold?

Some air purifiers are proven to capture mold spores and other allergens from the air.

Mold spores can cause respiratory problems and other health issues. Some air purifiers are proven effective at removing mold spores from the air by using HEPA filters or other technologies designed to capture and eliminate airborne particles. HEPA filters can capture particles of very small size, including mold spores.

Do air purifiers help with smell?

Some air purifiers can help with removing unpleasant odors and smells from the air.

Certain air purifiers are equipped gas-capture technologies such as activated carbon filters. Activated carbon absorbs and remove certain odors, gases, and chemical fumes from the air.

Activated carbon filters contain a porous material, such as activated charcoal, which traps and eliminates odors and volatile organic compounds (VOCs).

Where to place an air purifier?

To get the most out of an air purifier, it's important to place it in the right location.

If you're using an air purifier to address a specific source of pollution, such as smoke from a fireplace or cooking fumes, it's best to place the air purifier as close to the source as possible to capture the pollutants before they spread.

For general air cleaning, place the air purifier in the center of the room, away from walls or furniture, to allow for maximum airflow and coverage.

Does air purifier help with humidity?

An air purifier is not designed to directly help with humidity levels in the air.

An air purifier is not a substitute for a humidifier or dehumidifier if you are looking to control humidity levels in your home or office.

Do air purifiers help with wildfire smoke?

Yes, air purifiers can be effective in reducing the impact of wildfire smoke on indoor air quality. Wildfire smoke contains a variety of harmful pollutants, including fine particles (PM2.5), volatile organic compounds (VOCs), and other potentially toxic substances. Air purifiers with high-efficiency particulate air (HEPA) filters can effectively capture and remove these particles from the air.

Air purifiers with HEPA filters can be effective at removing many wildfire smoke particles from indoor air. Additionally, activated carbon filters, often included in air purifiers, can help reduce the levels of VOCs and odors associated with wildfire smoke.

When using an air purifier for wildfire smoke, it's important to choose a model with appropriate coverage for your room size and ensure that the device runs continuously in the affected areas. Keeping doors and windows closed also helps prevent outdoor smoke from infiltrating the indoor environment.

It's worth noting that while air purifiers can help to improve indoor air quality during wildfires, they may not eliminate all pollutants. Factors such as the proximity of the wildfire, the intensity of the smoke, and the overall ventilation in your home can affect the effectiveness of air purifiers. In severe cases, it may be advisable to seek additional measures or temporary relocation if the air quality poses a serious health risk.
