Description

NanoFIL NMA-12 UV Nano-Sterilizing Air Purifier in Metallic Grey and Starlight White

Developed in Hong Kong. Made in Hong Kong.

Only 20cm wide—fits perfectly on your nightstand without getting in the way.

A nano-sterilizing air purifier designed for small spaces. So quiet, you won't even notice it's on.

How does it compare to standard small purifiers?

NMA-12 (UV) VS Standard Mini Air Purifiers

Small doesn't mean compromising.

Plus, an extra layer of UV-C LED to handle any residual bacteria or viruses that pass through the filter.
20cm × 20cm base—fits on nightstands, office desks, or corners.
Sleep mode as low as 25dB, with screen brightness that dims automatically.

Standard Competitors

Physical filtration only; bacteria stay trapped on the filter surface.
Only one layer of protection.
Bulky floor models that take up too much space in small rooms.
Humming noise at night and blinding indicator lights.
Running it without knowing if it's actually working.
Parallel imports with expensive or hard-to-find replacement filters.

Why choose this one?

Four reasons to buy it

Compact, quiet, truly sterilizing, and transparent data.

Cylindrical air purifier on a bedroom nightstand, taking up minimal space

Selling Point 01

Designed for Hong Kong homes, it's just 20cm square.

Looking for an air purifier but finding that everything is either too big for the floor or won't fit on your nightstand? The NMA-12 measures 20cm(L) × 20cm(W) × 31.3cm(H)—about the size of a small trash bin. It fits perfectly on nightstands, desks, or office corners. Ideal for rooms up to 100 sq. ft., perfect for a bedroom or study.

Selling Point 02

More than just dust filtration: Filter + UV-C dual protection.

The biggest fear with air purifiers is that they just circulate air without cleaning it. The NMA-12 uses NanoFIL's proprietary nano-fiber electrospun filter, verified by third-party institutions (including SGS) to kill over 99.9% of common bacteria. Behind the filter, a UV-C LED handles any remaining bacteria or viruses. It also removes PM2.5 particles, formaldehyde, VOCs, and indoor odors.

Selling Point 03

25dB—won't wake you up while you sleep.

The most common failure of small purifiers is noise and glare—humming all night with a bright, distracting indicator light. The NMA-12's sleep mode runs as low as 25dB, similar to the ambient sound of a library. Once in sleep mode, the screen light dims automatically. You can sleep soundly without needing to tolerate the machine.

Selling Point 04

See the numbers, know it's working.

You've had it on for three months, but has it made a difference? How do you know? The NMA-12 has a built-in air quality sensor that displays real-time indoor data on the screen. It features three purification modes that adjust automatically based on conditions. It even alerts you when it's time to change the filter, so you don't have to keep track. Touch screen controls make switching modes easy.

You just finished renovations or bought new furniture and want to clear out formaldehyde and paint odors.
You are renting and don't want the hassle of moving a large appliance later.
You want to see actual air quality data rather than just hoping it works.
