5 Questions to Consider When Buying an Air Purifier
Air purifiers have a multitude of uses in the home, from removing foul odors to cleaning allergens, volatile organic compounds (VOCs), and gasses from the air. With so many air purifiers sold for in-home use, the process of researching various brands can be daunting. There are a few key things to consider when making your selection to help you find the right product.
What size air purifier do you need?
Are you looking for a whole-home solution, or are you purchasing just for one room? Are you open to buying multiple air purifiers for different rooms in your house, or do you need something portable you can move from room to room? The size of the room you’re trying to clean will have an impact on the devices you consider.
Additionally, you should consider if the actual size of the physical air purifier matters to you. If you have small children in the house, you may want something you can put up on a table or out of the way. Similarly, the physical design of some purifiers may make them more likely to tip over, which can be dangerous if they were placed in a nursery or playroom. Some devices work well when placed in the corner of a room, while others will function better in a more central location.
What is your budget for an air purifier?
There are air purifiers available for home use that run the gamut in terms of budget – ranging from under $50 to over $1,000. But be cautious of bargain buys, because you truly get what you pay for. When deciding your budget, it’s important to include replacement filters and electricity costs in your total calculation.
Consumer Reports recommends looking at the five-year cost for the best gauge of the total price. So while an air purifier may initially appear less expensive, the cost of owning the device over five years may be similar to a more expensive model.
What are you trying to improve about your air?
There are several traditional types of filters within air purifiers that have pros and cons depending on what you’re looking to improve about the air quality in your home. Feel like you have a funny odor in your home? Look for something that has a carbon filter. Worried about outgassing from your purifier? Stick with a mechanical purifier.
The most common types of traditional purifiers include:
- HEPA Filter: High-Efficiency Particulate Air (HEPA) filters effectively filter up to 99.97% of airborne particles down to 300 nanometers. This works best for dust, pollen, pet dander, and other airborne particle pollutants. Be cautious of HEPA-like alternatives if you are shopping for this type of filter.
ULPA Filter: More effective than HEPA filters, Ultra-Low Particulate Air (ULPA) filters are a type of mechanical filter that can capture up to 99.999% of particles down to 100 nanometers.
Activated Carbon Filters: Activated carbon filtration can be effective at removing smoke, cooking odors, or harmful VOCs from your home.
Electrostatic and Ionizing Cleaners: This genre of air purifier emits negatively charged ions which attach to floating pollutants to remove them from the air.
- Ultraviolet Air Purification: As the name suggests, these filters use UV light to destroy some airborne viruses and bacteria. They are often combined with other filter types and may generate ozone as a byproduct. Prolonged exposure to ozone can be harmful, though some manufacturers claim they are ozone free.
In addition to an oversized activated Carbon Filter and a Pre Filter to capture larger particulates and gasses, the G200 also includes a patented Core Filter that is unique to Celios and is not available in any other at-home air purifier. Using only mechanical filtration, this three filter system allows the device to produce cleanroom quality air in your own home. It can capture up to 99.99999% of particles. And it can filter materials down to 10 nanometers. That’s up to 3,000 times more effective than HEPA standards (and can capture particles up to 30 times smaller).
Do you have specific allergies or environmental factors affecting the air in your home?
If you have specific allergens you’re trying to eliminate from your home, that could largely influence what products would be best. Similarly, if you live in an area where storms are common or your region is prone to wildfires, that could also inform your shopping.
If you have allergies or asthma, specific purifiers are designed for allergy relief or to remove pollutants from the air. For chemical sensitivities, you may want to consider a model that prioritizes chemical filtration, and does not off-gas any chemicals as it cleans. As outlined above, some combination of a carbon filter and mechanical filter will offer the best protection against both particles and gases – without producing harmful substances as a byproduct.
What air purifier features do you need?
Beyond the science of the device, there may be certain special features or extras that you’re looking for. We already mentioned that the mobility of the device might be an important factor if you’re looking to move one device around your home. With its two Smart Lithium Ion batteries, the Celios G200 can run up to 24 hours unplugged, so you can take it wherever you go.
Other features to consider include if the device has a remote, if it is wifi-enabled, or – if you’d like to go full smart-house – if it is compatible with Alexa. Many devices also offer adjustable fan speeds or night mode for a more incognito experience.
