Six Maruti Suzuki models are covered: Alto, Swift, Swift (2015–2017), Brezza, Ciaz, and Ertiga. The 2015–17 Swift and the current Swift use different housing sizes, so they appear as separate listings. Pick your exact model and year at checkout. Swift owners in particular should check this carefully so they do not order the wrong unit.

There is no fixed schedule. It depends on how often you drive and the air quality in your area. Maruti cars are among the most used daily commuters in India, which means the filter loads up faster in polluted cities. Keep a Prana Air monitor inside the cabin with the AC on. When PM2.5 stays high, the filter needs changing.

The main signs are reduced airflow, most noticeable in the compact Alto and Swift, a musty smell from the vents, and a windscreen that defogs slowly. In the Ertiga and Brezza, a choked filter can also make the AC take longer to cool the cabin. The Prana Air filter is rated up to 99% efficient against PM2.5. Note the cabin reading before and after fitting with a PM2.5 air quality monitor to confirm the real-world performance.

Yes. Maruti's factory filters take care of basic dust filtration, but they have no activated carbon layer, which is a standard gap across the range. So exhaust fumes, two-wheeler emissions, and traffic VOCs enter the cabin unfiltered. The Prana Air filter adds HEPA-grade particulate media along with an activated carbon layer, handling both particle and gaseous pollution at a similar replacement cost.

Yes. Maruti cars are among the easiest to service at home. In the Swift, Brezza, Ciaz, and Ertiga, press the glove box side tabs, lower the compartment fully, and the filter slides straight out. The Alto follows the same method, with small differences by year. Put in the Prana Air filter with the airflow arrow pointing towards the blower. No tools required, and it takes 5–10 minutes.

Since the filter is a consumable, it does not come with a performance warranty. Its life depends on how often you drive and on the local air quality. However, if the filter reaches you with a fitting issue or any physical damage at the time of delivery, we will replace it free of cost. Please check it as soon as you receive it and contact us immediately if anything is wrong.

There is a marginal drop in airflow, since the filter uses high-efficiency media. We have designed it to give the best possible balance between maximum air purification and steady AC and heater performance.
