Devanti Air Purifier — H11 HEPA, CADR 180m³/h, Small Room | AU

The Devanti Air Purifier is a budget-friendly small-room HEPA air purifier with an air quality sensor, four operating modes, and an optional ioniser stage. Built around an H11 HEPA filter and an activated carbon layer — accessible price point for households starting out with HEPA filtration in a bedroom, study, or kids' room.

Allergy relief benefits

• H11 HEPA filtration captures ≥95% of airborne dust mite debris, pollen, pet dander and mould spores at 0.3μm — sufficient for everyday household allergen filtration in a small room
• Activated carbon filter adsorbs household odours, smoke, and common VOCs that can irritate sensitive airways
• Washable pre-filter captures pet hair and large dander before the HEPA — extends HEPA filter life in shedding-pet households
• Air quality sensor with colour-coded indicator (good / fair / poor) lets allergy sufferers see when ambient allergen load is high
• Auto mode ramps up airflow when sensors detect particles — automatic response during pollen surges or dusty conditions
• Silent mode designed for low-noise overnight bedroom use, when dust mite allergen exposure is highest
• Switchable ioniser — can be turned off for asthma or respiratory-sensitive users (see Safety note below)
• 8-hour timer + remote control — set-and-forget operation for bedrooms and nurseries

A note on filter grade

This unit uses an EN 1822 H11 grade HEPA filter — captures ≥95% of particles at MPPS (most penetrating particle size). H11 is one step below "True HEPA" (H13, ≥99.95%). For everyday household dust, pollen, and pet dander filtration in a single small room, H11 is sufficient. For medical-grade air purification at the H13 standard, see our SmartAir or Ionmax H13 ranges.

FAQs

Who is the Devanti Air Purifier designed for? Allergy sufferers wanting a budget-friendly HEPA-filtered air purifier for a single small room — bedrooms, studies, kids' rooms, nurseries, or studios up to ~12 m² floor area. Particularly useful in dust-mite-allergy households alongside encasement bedding; pollen-allergy sufferers during peak seasons; and households with light pet dander or smoke exposure. The auto mode and air quality sensor suit users who want set-and-forget operation. Not suited to large living areas, open-plan spaces, or commercial settings — see our SmartAir Blast range for those.

What does H11 grade mean? H11 is an EN 1822 HEPA filter classification. H11 captures ≥95% of particles at MPPS (the most penetrating particle size, around 0.1-0.3 microns). It's one step below H13 ("True HEPA," ≥99.95%). For everyday allergen and dust filtration in a small room, H11 is sufficient. For higher-grade H13 filtration, see our SmartAir or Ionmax H13 units.

Does the ioniser produce ozone? Yes — ionisers (negative ion generators) can produce trace ozone as a by-product, which can aggravate asthma or respiratory sensitivity. Devanti hasn't published an ozone emission figure for this unit. If ozone is a concern, switch the ioniser off and run the unit on its HEPA + carbon filtration only. For an ozone-free purifier with no ioniser stage, see our SmartAir Sqair or SA-600.

Is it loud? Quiet on Silent mode — suitable for overnight bedroom use. Louder on Efficient mode (high speed). Most owners run it on Auto, which adjusts based on detected air quality. Devanti hasn't published precise dB figures.

How often should I replace the filter? Devanti's general guidance is once a year under normal household use. The filter change indicator on the unit will signal when replacement is due. Replacement filter sets are sold separately. A version of this listing bundled with a spare filter is also available.

Is it good for allergies? The H11 HEPA filter captures airborne dust mite debris, pollen, pet dander, and mould spores at 0.3 microns per the EN 1822 H11 specification (≥95%). The activated carbon filter adsorbs household odours and VOCs. We don't claim it treats allergies — that's a medical question — but H11 HEPA filtration is the construction allergy-conscious households use in small rooms. For higher-grade H13 filtration, see our SmartAir or Ionmax H13 ranges.

Care notes

Replace the H11 HEPA / carbon filter set every ~6-12 months under normal household use, or sooner if the filter change indicator activates. Don't wash the HEPA filter — replace it. Vacuum the pre-filter monthly to extend HEPA life. Wipe the cabinet with a dry cloth.
