Frequently Asked Questions About Air Purifiers in Singapore
How do I know if I need an air purifier?
If you have allergies or asthma, an air purifier can alleviate symptoms like sneezing, coughing, and itchy eyes by improving air quality. A humidifier with air purifier features can also reduce sinus inflammation caused by allergens in dry air.
How effective is an air purifier for dust removal?
Many air purifiers for dust removal are highly effective. They often contain a HEPA filter, which captures 99.9% of dust particles as small as 0.3 microns in size, significantly reducing airborne dust and improving your indoor air quality. These filters are also present in vacuum cleaners to remove dust and allergens before they circulate in the air.
What size air purifier do I need for my room?
When choosing an air purifier for a room, the two-thirds rule is a good general guide. Choose an air purifier with a Clean Air Delivery Rate (CADR) of at least two-thirds of the room's square footage. For example, a room of approximately 40 sqm would require a minimum CADR of about 260.
How do air purifiers help with pet dander and odours?
Air purifiers for pets often include HEPA filters that capture the particles that cause odours, such as pet dander, and prevent them from recirculating. This freshens the air and reduces allergens and smells in your home.
