Frequently asked questions

Title

Difference b/w Summer & Winter version of Split AC Purifier?

The summer version is best used when the PM2.5 is below 300, featuring a single HEPA filter to remove dust, pollen, and allergens during cooling. The winter, ideal for PM2.5 levels above 300 in fan mode, comes with double HEPA filters for 2X filtration power, effectively tackling smog, germs, and viruses. Both are designed for seasonal air purification tailored to specific conditions.

Is AIRTH selling AC?

AIRTH offers an AC air purification device that upgrades your existing AC type to also purify air. It is an add-on product, developed by researchers at IIT Kanpur and IISc Bangalore, designed to remove pollutants like dust, allergens, and bacteria from the air without affecting your AC’s cooling or efficiency.

In short: You keep your AC — AIRTH just makes its air cleaner.

Will AC electricity consumption increase if I use AIRTH Purifier?

During summer season, there will be 1% increase in electricity cost of AC which is INR 250 per month.

During winter season, use your AC in fan mode where electricity consumption is just 40W.

When you consider running conventional air purifier you would be saving electricity cost.

I have a new AC. Do I still need the AIRTH AC Purifier?

Yes!

Your AC’s built-in mesh filter is not designed to provide clean air—it only captures large dust particles. The AIRTH AC Purifier upgrades your AC into a powerful air purifier, effectively removing fine dust, allergens, and pollutants. It also extends your AC’s lifespan and reduces maintenance by preventing dust buildup in the mesh filter.

Will using the AIRTH AC Purifier void my new AC warranty?

No, the AIRTH AC Purifier does not interfere with your AC’s internal components or functionality. It is an external add-on filter designed for easy installation without any modifications to your AC unit. Your AC warranty remains intact while you enjoy cleaner air and reduced maintenance.

How do you operate the Split AC Purifier in winter?

To use the Split AC Purifier during winter:

Ensure proper installation: Make sure the purifier is securely placed on the AC's inlet grill.
Switch your AC to fan mode: Since cooling isn't required in winter, run your AC in fan mode to circulate and purify the air.
Benefit from double HEPA filtration: The winter version comes with 2 HEPA filters, providing 2X filtration power to remove smog, germs, and harmful particles.
No extra power needed: The purifier works without additional electricity or batteries, making it cost-effective during colder months.

This ensures clean, healthy air even when the AC isn't cooling.

What is the installation process for integrating the AIRTH Split AC Air Purifier?

For the Summer Version:

Ensure that your AC's mesh filter is clean before installing the AIRTH AC Filter.
Remove the Split AC Air Purifier for Summer from its cover and peel off the adhesive paper from both magnetic strips.
Place the Split AC Air Purifier for Summer on the top-center of your Split AC.
Turn on your AC and enjoy clean, fresh air.

For the Winter Version:

Ensure that your AC's mesh filter is clean before installing the AIRTH AC Filter.
Remove the Split AC Air Purifier for Winter from its cover (it consists of two parts) and peel off the adhesive paper from each of the four magnetic strips.
Install the Split AC Air Purifier on top of your AC.
Turn on your AC.
Set your AC to fan mode, and you're all set!

Is the AIRTH purifier filter compatible with my AC?

The dimensions of the AIRTH HEPA Filter are as follows: 52D x 20W x 5H Centimeters. The AIRTH AC Air Purifier is compatible with all Split ACs.

AIRTH Summer Version is smaller than my AC inlet. Will it be able to provide clean air?

The Summer version is intentionally designed to allow space for air suction, as ACs operate on the principle of air recirculation, which cools the air as it passes through the system. When the AIRTH Summer version is installed, air flows through the filter multiple times per second, ensuring simultaneous cooling and purification during the process.
