Frequently asked questions about the Air cleaners category
What are Air cleaners and what are they used for?
Air cleaners — are devices that remove dust, allergens and odors from indoor air. They use HEPA filters, carbon cartridges and fans to improve air quality in homes and apartments and reduce airborne dust and allergens.
How do Air cleaners with HEPA filters differ from models without them?
Air cleaners with HEPA filters capture up to 99.97% of 0.3 µm particles, making them effective against dust, pollen and dust mites. Models without HEPA typically rely on carbon or electrostatic filters and are less effective at removing fine particulate matter and allergens.
Are household Air cleaners suitable for an apartment?
Yes, household Air cleaners are suitable for apartments: choose a model sized for the room area (CADR or recommended coverage is usually provided). For a typical 20–30 m² room, a compact HEPA cleaner with a CADR around 200 m³/h is appropriate.
Which models are best for allergy and asthma sufferers?
For allergy and asthma sufferers, choose Air cleaners with True HEPA H13–H14 and an activated carbon prefilter to remove odors and gases. Look for high CADR, a quiet night mode and a filter replacement indicator.
How do Xiaomi Air cleaners differ from other brands?
Xiaomi Air cleaners commonly feature HEPA and activated carbon filters plus smart control via an app. Compared with basic models they often include smart-home integration and additional operating modes.
What does an Air cleaner rating mean and how to use it when choosing?
A rating typically combines CADR, filtration efficiency and user reviews. When choosing, check CADR for dust/smoke, filter type (HEPA, carbon) and real feedback about noise and reliability.
Can Air cleaners be used against odours and gases?
Yes, to remove odours and gases choose an Air cleaner with an activated carbon filter. The carbon layer is effective for household odours and many volatile organic compounds when filters are replaced regularly.
Are Air cleaners suitable for use near a kitchen stove or a smoker in an apartment?
Air cleaners with high CADR and a carbon filter help reduce cooking odours and fine particles from tobacco smoke. They will not fully remove large aerosols and soot, so combining them with good ventilation is recommended.
Which filters need replacement and how often in an Air cleaner?
Typically HEPA and carbon filters require replacement: the recommended interval is usually 6–12 months for household use. Exact timing depends on air load and manufacturer instructions; check the filter replacement indicator.
Are Air cleaners suitable for spaces with internal combustion engines or workshops?
Spaces with exhaust gases or engine particulates require industrial or specialised cleaners with high filtration capacity and adequate CADR. Household models handle dust and odours but do not replace professional equipment for harmful gases and fine soot.
Which parameters (CADR, area) are important when choosing an Air cleaner for an apartment?
Consider CADR (cleaning rate, m³/h) and the recommended coverage area (m²). For precise sizing multiply room volume (m³) by desired air changes per hour (apartments typically 3–5 ACH) and choose a model with a matching CADR.
