How Sanitify's 4-Stage Clean Air Process Works

The first line of defence is a washable, reusable pre-filter mesh designed to capture large airborne particles before they reach the more sensitive filtration layers downstream. This stage intercepts dust bunnies, pet hair, human hair, lint fibres, and large pollen grains that would otherwise clog and degrade finer filters prematurely.

By removing these coarse particles early, the pre-filter significantly extends the operational lifespan of both the HEPA and activated carbon stages, reducing your ongoing maintenance costs and environmental footprint. Simply rinse under running water every two to four weeks and allow it to air-dry completely before reinserting.

• Captures dust, pet hair, lint, and large pollen
• Washable and reusable for the lifetime of the device
• Extends HEPA and carbon filter life by up to 40%

At the core of Sanitify sits a medical-grade HEPA H13 filter, the same classification used in hospital operating theatres, pharmaceutical clean rooms, and laboratory environments. This dense fibre matrix captures 99.97% of airborne particles down to 0.3 microns in diameter, which is the most penetrating particle size and the hardest to trap.

This means PM2.5 fine particulate matter, fine pollen, mould spores, bacteria, and even virus-bearing aerosol droplets are intercepted with near-perfect efficiency. For allergy sufferers, asthma patients, and anyone living in areas with high outdoor pollution, this stage provides the critical barrier between outside contamination and the air you breathe indoors. The filter should be replaced every six to eight months for optimal performance.

• 99.97% removal of particles at 0.3 microns
• Traps PM2.5, pollen, bacteria, and virus-bearing aerosols
• Medical-grade classification used in hospital environments

While HEPA excels at trapping solid particles, gases and chemical vapours pass straight through fibre filters. That is where the activated carbon layer comes in. Packed with millions of microscopic pores, activated carbon works through adsorption, a chemical process where gas molecules bond directly to the carbon surface and are held there permanently.

This stage neutralises volatile organic compounds (VOCs) emitted by paint, cleaning products, furniture, and building materials. It also eliminates cooking fumes, formaldehyde off-gassing from new furnishings, tobacco and vaping residues, and persistent household odours. The result is air that not only tests clean on a particle counter, but genuinely smells fresh and pure without masking fragrances or chemical deodorisers.

• Eliminates cooking fumes, smoke, and persistent odours
• No masking fragrances needed, genuinely pure air
