Frequently Asked Questions
Air purifiers work by pulling in air and passing it through multiple filters to trap dust, allergens, smoke, and bacteria. Some models also use UV light or ionisation to neutralise airborne pollutants. This process helps improve indoor air quality by reducing harmful particles and odours, making the environment healthier and fresher.
A HEPA (High-Efficiency Particulate Air) purifier uses a dense filter to capture 99.97% of airborne particles as small as 0.3 microns, including dust, pollen, pet dander, and bacteria. The tightly woven fibres in the HEPA filter trap pollutants, ensuring cleaner and safer air, which is especially beneficial for allergy sufferers and those with respiratory issues.
Most air purifiers last 5–10 years with proper maintenance. Their lifespan depends on build quality, usage frequency, and timely filter replacement. Regular cleaning and servicing help maintain performance, ensuring the purifier continues delivering clean, efficient airflow throughout its operational life.
Yes, most modern air purifiers are energy efficient, typically consuming 20–60 watts on average settings. Energy Star–rated models use even less power. Running them continuously on low or auto mode ensures effective purification without significantly increasing your electricity bill.
Yes, you can safely keep an air purifier on all night. Modern purifiers are designed for continuous use, ensuring cleaner air while you sleep. With quiet operation and energy‑efficient filters, they remove dust, allergens, and pollutants throughout the night, improving breathing comfort and sleep quality.
The basics of an air purifier include a HEPA filter for trapping fine particles, an activated carbon filter for odours, and a fan system that circulates clean air. Key specifications also cover CADR (Clean Air Delivery Rate), coverage area, and noise levels. Together, these features ensure effective removal of dust, smoke, pollen, and pet dander.
Avoid air purifiers that lack HEPA filters, have low CADR ratings, or limited coverage area. Models with high noise levels or expensive, hard‑to‑replace filters can also be inconvenient. Ioniser‑only purifiers may produce ozone, which is harmful indoors. Always choose reliable brands with proper certifications and easy maintenance.
Yes, it is safe to sleep near an air purifier. These devices are built for continuous operation and improve indoor air quality overnight. Quiet models with low noise levels ensure restful sleep while removing allergens and pollutants. Positioning the purifier a few feet away helps maximise airflow without disturbance.
