The Odorstop HEPA Air Purifier combines five proven air cleaning technologies in one compact unit. This white tower design measures 25.4cm x 25.4cm x 40.6cm and weighs just 1.8kg.
The H13 HEPA filter captures particles as small as 0.3 microns whilst the UV light technology kills bacteria, fungus and viruses. Active carbon filtration removes household odours effectively.
Features include five speed settings, auto mode that adjusts based on air quality, sleep mode for quiet overnight operation and a timer function. The 360-degree air intake maximises cleaning efficiency for rooms up to 93 square metres.
The OSAP5 effectively purifies air in rooms up to 93 square metres (1000 square feet). The 360-degree air intake design maximises circulation efficiency, making it suitable for large living rooms, bedrooms, or open-plan areas. For optimal performance in larger spaces, position the unit centrally with adequate clearance around all sides.
HEPA filter replacement depends on usage and air quality conditions, typically every 6-12 months. The unit doesn't include a filter replacement indicator, so monitor performance and check filters visually. Heavy use environments with pets, smoking, or high dust levels may require more frequent changes. Replacement H13 HEPA filters are available separately from Odorstop.
The UV-C light technology kills microorganisms without producing harmful ozone emissions. The unit is CARB certified, meeting California's strict air quality standards for ozone-safe operation. The UV light works internally within the sealed unit, so there's no direct UV exposure risk to users or pets during normal operation.
Speed settings 1-3 operate very quietly, comparable to a whisper or gentle breeze. Users report being able to watch television and hold conversations without interference. Speeds 4-5 produce more noticeable fan noise similar to a small desktop fan, but remain acceptable for most situations. Sleep mode minimises noise for overnight use.
Yes, the blue air quality indicator lights can be dimmed or turned off completely. This feature is particularly useful for bedroom use where light sensitivity might disturb sleep. The lights change colour to indicate air quality status - blue for clean air, with colour changes when particles are detected.
No, the OSAP5 requires manual restart after power failures. The unit doesn't resume previous settings automatically, so you'll need to turn it back on and select your preferred speed or auto mode. This safety feature prevents unexpected operation but means the unit won't continue purifying air during extended absences after power interruptions.
The active carbon filter effectively removes common household odours including cooking smells, pet odours, smoke and chemical vapours. It's particularly effective against woodstove smoke and kitchen odours. The carbon filtration works alongside HEPA and UV technologies to provide comprehensive air cleaning, though extremely strong odours may require additional ventilation.
The H13 HEPA filtration captures 99.97% of particles down to 0.3 microns, including common allergens like pollen, dust mites and pet dander. Combined with UV sterilisation, it provides medical-grade air cleaning suitable for allergy sufferers. However, those with severe sensitivities should consult healthcare providers and consider the unit as part of a broader allergen management strategy.
