Most purifiers trap bacteria on the filter, leave it alive, and push the same air back into your room. BIOGUARD kills it first, with Silver-Copper protection and a UV-C chamber, so the air coming out is genuinely clean, not just filtered. Covers up to 1,700 sq.ft, quiet enough to forget it is on.

Why families choose Bioguard

A nursery doesn't need a purifier that traps bacteria. It needs one that gets rid of them. BIOGUARD is built for the rooms where it matters most, your child's bedroom, your parents' room, the space where someone in the house is always a little more vulnerable. Clinics trust it for the same reason you should.

FAQs

Please read our FAQs page to find out more.

Is the KyoAir BIOGUARD safe for newborns and infants?

Yes. The BIOGUARD was built specifically for newborn nurseries and pediatric environments. It produces zero ozone, runs at under 23 dB in sleep mode, and its Silver-Copper AgCu Guard antimicrobial technology ensures the air leaving the machine is biologically safe, not just filtered. It also includes a Child Lock for added peace of mind.

What makes the BIOGUARD different from a regular HEPA air purifier?

A standard HEPA purifier traps bacteria and viruses on its filter and leaves them there, alive.
The BIOGUARD actively inhibits microbial growth inside the filtration system using Silver-Copper AgCu Guard technology, then neutralises surviving pathogens in a dedicated UV-C sterilisation chamber. Five layers of filtration. One machine that actually finishes the job.

What pollutants does the BIOGUARD remove?

The full spectrum. Dust, allergens, smoke, bacteria, viruses, mould spores, PM2.5, pet dander, VOCs, formaldehyde, and harmful gases. The 7-Step BioShield system combines MacroBlock, TRUE HEPA
H13, NanoCapture, OxyLayer, Hydro Ioniser, UV ioniser and Dual KyoAir IonCore, covering particle threats, biological threats, and chemical pollutants that HEPA alone cannot address.

How large a room can the BIOGUARD cover, and how quiet is it?

The BIOGUARD covers up to 1,700 sq.ft with a CADR of 488 m³/h, making it one of the most powerful purifiers in its class for large bedrooms, living areas, and clinics. In sleep mode it operates at under 23 dB, quieter than a library, so it runs continuously without disturbing sleep or rest.

How long does the filter last?

Filter life depends on your conditions rather than a fixed schedule: cleaner air and smaller rooms extend it, while heavy pollution and larger open spaces shorten it. In typical Indian homes, this means many months of service. KyoAir filters are built to the highest standard using the most durable materials available, maintaining their efficiency throughout that period. Every unit also ships with two additional sets of filters included, and the built-in filter life indicator confirms precisely when a replacement is due.
