Rising air pollution has made clean indoor air an important concern in Indian homes. This, in turn, has made an air purifier one of the must have appliances. That said, choosing an air purifier is not just about picking a machine with a filter or two. It's about getting a device with the right filtration system and smart features that cleans the indoor air while adding convenience to everyday life. So, when I to bring an air purifier to my home, I not only look for HEPA filter but also smart features.

Simply put, I an air purifier that offered better control over the air inside my home while making everyday operation easier. This meant having features such as real-time air quality monitoring, app connectivity, automatic fan-speed adjustment and filter-life indicators - features that would help me keep a track of indoor air conditions without having to check the machine constantly.

However, I didn't choose an air purifier based on its smart features alone. Its ability to clean the air effectively mattered just as much. I also weighed into factors such as Clean Air Delivery Rate (CADR), recommended room coverage, filtration technology, noise output and replacement filter costs. After all, an expensive connected air purifier may not necessarily be the right fit for every home or room size.

After much research, I found five smart air purifiers I'd consider buying for my home.

Factors to consider while buying an air purifier

- CADR (Clean Air Delivery Rate): CADR indicates how quickly an air purifier can deliver filtered air. A higher CADR generally means faster air cleaning. Choose a model with a CADR suitable for your room size and pollution levels.

- Room coverage area: Check the manufacturer's recommended coverage area before buying. A purifier designed for a small bedroom may not be effective in a large living room.

- HEPA filtration technology: Look for a genuine HEPA filtration system that can capture fine airborne particles. HEPA filters are particularly useful for trapping dust, pollen and other airborne allergens.

- Filters beyond HEPA: Different filters serve different purposes. A pre-filter captures larger particles such as hair, lint and visible dust, while an activated carbon filter helps reduce certain odours, smoke and gaseous pollutants. Simply put, a multi-stage filtration system can offer more comprehensive air cleaning.

- Real-time AQI: Smart air purifiers with built-in sensors can display indoor air quality readings. They can also help you adjust the fan speed as per real-time conditions. You can check these details on the device or through a companion app.

- Smart connectivity and app control: If convenience matters, consider a Wi-Fi-enabled air purifier with smartphone app support. Depending on the model, you may be able to: monitor indoor air quality remotely, adjust fan speed and operating modes, schedule purification cycles, receive filter replacement notifications and track air quality trends.

- Filter replacement cost and availability: Air purifier filters require periodic replacement, which makes maintenance an important ownership expense. Before buying, check replacement filter prices, recommended replacement intervals, availability of genuine filters in India and filter-life indicators and replacement alerts.
