WHY INDOOR AIR MATTERS

Your room may look clean.
The air can still be polluted.

Pollution doesn't disappear at your front door. Fine particles from outdoor smog and indoor activities can remain suspended inside closed rooms.

01

WITHOUT FILTRATION

Ordinary AC airflow alone isn't purification

• Standard AC mesh filters mainly catch larger dust
• Fine pollution can continue recirculating
• Winter windows often stay shut

02

WITH AIRTH WINTER

Turn circulation into filtration

• Dual HEPA filters capture fine airborne particles
• Existing AC fan recirculates room air through FILTRIX®
• Use fan mode without active cooling

THE WINTER DIFFERENCE

Engineered for winter.
Designed for everyday life.

Dual-layer FILTRIX® HEPA

Two HEPA filter layers provide the winter configuration intended for periods of heavy air pollution and help capture airborne particulate matter.

Winter-ready fan mode

When cooling isn't needed, run your split AC in fan mode to circulate room air through the filter.

Simple, universal fit

Retrofit your existing split AC using AIRTH's frame mounted above the air inlet—without making changes inside the AC.

Smarter filter care

The integrated time indicator supports filter-life tracking. Clean and replace the filters based on condition and usage.

Akash Singh

Didn’t expect such a noticeable difference. Within a few days, the air felt lighter and less dusty—especially in the mornings. Installation took barely 5 minutes.

Megha Sharma

I bought this mainly because of Delhi pollution, and honestly, it works. My room doesn’t feel stuffy anymore, and I wake up without that dry throat feeling.

Amit Verma

Super simple product but very effective. No noise, no maintenance headache, just clean air through the AC. Worth it for the price.

Ayushi Arora

Perfect alternative to expensive air purifiers. I didn’t want another bulky device, and this does the same job using the AC itself.

GOOD TO KNOW

A little more clarity.

Straight answers before upgrading your split AC.

How does the AIRTH Winter Edition work?

AIRTH's Winter Edition attaches above the existing split AC inlet. The AC recirculates indoor air through two HEPA filter layers so particles can be captured as air passes through.

Can I use it without cooling the room?

Yes. When cooling is not required, use your AC in fan mode. This recirculates the indoor air through the filters without intentionally cooling the room.

How are Summer and Winter Editions different?

The winter configuration uses two HEPA filters for higher-pollution periods. The summer configuration uses one filter to preserve more inlet opening and cooling airflow.

Will it fit my split AC?

The standard AIRTH split AC frame is intended to fit different split AC tonnages. Check the installation guide and confirm clearance above your unit.

When should I replace the filters?

Typical filter replacement guidance is around 8–12 months, depending on pollution and operating time. The time indicator can help you monitor usage.
