I still remember the day I bought an air purifier. The Delhi winter haze was settling in, and I was worried, watching my elderly parents struggle with coughs. Even I, otherwise healthy, was facing breathing difficulty indoors. And as you know, air quality isn’t just a seasonal worry anymore. So an air purifier can be a year-round health shield, especially for vulnerable lungs. I wanted the peace of mind that every breath in our home would be cleaner, so I went hunting for the top purifier for our family. Now, I want to help you do the same.
SurveyWhile researching, what I found is that the ‘top’ purifier largely depends on your budget and room size. High-end models pack in features like heating/cooling and fancy apps, while budget models focus on core purification power. Below is a descending list of top picks by price bracket, from under Rs 70,000 all the way to under Rs 10,000, with one Top Choice and one Runner-Up in each category. Each description notes key specs (room coverage, CADR, filter, noise, power, etc.) so you can match a model to your budget and needs. I hope you find one that suits your home and helps your family breathe easier.
This list is not based on internal testing.
Under Rs 70,000
Top Choice: Dyson Purifier Hot+Cool HP12 (about Rs 68,900)
The Dyson HP12 is pitched as a premium 3-in-1 device combining purification, heating and cooling. It uses a fully sealed HEPA H13 filter along with what Dyson calls a K-Carbon filter, which it claims can capture up to 50% more nitrogen dioxide than standard carbon filters and also break down formaldehyde. The Air Multiplier system is said to project over 290 litres of airflow per second, with up to 350° oscillation for whole-room coverage (roughly 300 sq.ft, depending on layout). It supports the MyDyson app and major voice assistants, offering remote control and live air-quality data. On low settings, it could remain quiet enough for night use, and the bladeless design may be safer around children and pets. The main drawback is that published CADR figures are limited, so in very large open rooms, it may not achieve fast air changes per hour compared with high-CADR purifiers. Dyson recommends renewing filters every 12 months. The HP12 could make sense if you want heating and cooling built in, rather than pure CADR speed.
Runner-Up: Dyson Purifier Big+Quiet BP02 (about Rs 68,900)
The Dyson Big+Quiet BP02 is described as a high-end purifier designed for large spaces, with Dyson claiming coverage up to about 1,076 sq.ft under its own test conditions. It uses a HEPA H13-grade filter plus a K-Carbon filter in a sealed air-path system, and Dyson states this can remove 99.95% of ultrafine particles as small as 0.1 microns. Long-range projection and Air Multiplier airflow aim to distribute clean air across bigger rooms. It includes live air-quality sensing (PM2.5, PM10, VOCs, NO₂), an LCD screen, the MyDyson app and voice support. Dyson lists maximum noise around 56 dB and power use of about 50 W. The company also claims the HEPA filter can last up to 5 years, with the carbon filter lasting up to 2 years. However, the absence of clear third-party CADR figures means its ACH performance in a large open room may be harder to estimate. It could suit users who want large-room coverage and quiet operation, but pure high-CADR models may offer quicker cleaning for the money.

Under Rs 50,000
Top Choice: Shark Clean Sense HP132 (about Rs 45,000)
Shark’s Clean Sense HP132 could be a strong performer in this bracket. It is rated for roughly 680 sq.ft and uses a True HEPA filter that Shark claims can capture 99.98% of particles in the 0.1–0.2 µm range. The “Odour Neutraliser” add-on could help tackle pet or cooking smells. Its CADR is said to be about 161 cfm (around 273 m³/h), which should be enough to cycle a medium-sized room multiple times per hour. It includes four fan speeds and an auto mode driven by a particle sensor. Shark lists a maximum noise of roughly 40–50 dB on high. There’s no Wi-Fi app here, so it focuses purely on cleaning. Its mix of real HEPA filtration, decent coverage and controlled noise makes it a solid choice at this price.
Runner-Up: Dyson Purifier Cool PC1 (about Rs 40,000)
The Dyson Purifier Cool PC1 is said to be suitable for rooms around 270 sq.ft. It uses a sealed HEPA H13 filter with activated carbon, which Dyson says can capture 99.95% of particles as small as 0.1 microns while removing gases and odours. It also uses the Air Multiplier system and 350° oscillation to help push clean air throughout the room. Smart features include built-in PM and gas sensors, auto mode, night mode, the MyDyson app and voice control. As with other Dyson models, independent CADR and ACH figures are not widely published, so large-room performance may vary. The PC1 could be useful for users who want Dyson’s design and smart controls rather than maximum airflow output.
Under Rs 30,000
Top Choice: Philips AC4221 Smart Air Purifier (about Rs 25,899)
The Philips AC4221 is positioned as a high-airflow machine. Philips claims a CADR of around 600 m³/h thanks to its dual-fan design, which is said to cover up to 72 m² (about 775 sq.ft). This could allow up to five air changes per hour in many living rooms. It uses NanoProtect HEPA filtration rated to remove 99.97% of fine particles, and includes an activated carbon layer for gases. It is ECARF-certified for allergy reduction. Philips states noise starts at 15 dB on low and reaches about 51 dB on high. The filter life is claimed to be about 9,000 hours (roughly two years). Replacement filters cost about Rs 4,500. Smart features include app control, auto mode and a live AQI display. It is a large machine and its high setting can be audible, but for fast cleaning, the AC4221 is said to be very effective.
Runner-Up: Coway AirMega Storm AP-1220B (about Rs 27,999)
The Coway AirMega Storm is rated for about 575 sq.ft and uses a Green True HEPA filter that Coway claims can capture up to 99.99% of fine particles and viruses. Its CADR is listed at about 223 m³/h for cigarette smoke. Coway rates it for rooms around 53 m² and claims it can still reach around 5 ACH in such spaces. A key advantage is the 8,500-hour filter life (about 1.5–2 years). Replacement filters cost about Rs 5,500, giving an annual running cost of roughly Rs 2,700. Noise is said to peak at about 49 dB, and drop to around 22 dB on low. It also includes auto mode, sensors and a 7-year motor warranty. It could be ideal for users who prefer quiet operation and long-term reliability over maximum CADR.
Under Rs 15,000
Top Choice: Xiaomi Smart Air Purifier 4 (Rs 14,999)
The Xiaomi Smart Air Purifier 4 is rated for about 48 m² (516 sq.ft) and offers a claimed CADR of about 400 m³/h. Xiaomi states it can clean a 20 m² room in roughly 10 minutes. The 3-in-1 filter uses H13-grade filtration and an activated carbon layer. Xiaomi claims it can remove 99.97% of 0.3 µm particles. It also includes a built-in VOC sensor that could improve auto-mode responsiveness, plus an optional ioniser. Smart features include Wi-Fi control, app integration, voice assistant support, PM2.5 display and a night mode. Noise can be as low as 32.1 dB. Filters typically need replacing every 6–12 months and cost around Rs 3,000. It could be the right choice if you want strong airflow plus rich smart features.
Runner-Up: Coway AirMega 150 (AP-1019C) (Rs 17,999)
The Coway AirMega 150 is suitable for medium bedrooms and home offices of about 33 m² (355 sq.ft). It uses a 4-stage system including a prefilter, carbon filter and Anti-Flu True HEPA filter. Its CADR is rated at about 303 m³/h, which should deliver close to 5 ACH in most medium rooms. One of its biggest advantages is filter life: Coway claims up to 8,500 hours, or roughly two years of typical use. The prefilter is washable, which helps extend cartridge life. Noise is said to start at 22 dB in whisper mode. Power use is about 38 W. There is no app control here, but the colour-coded air quality indicator and auto mode keep operation simple. It could be a good fit if you prefer low noise and long filter life.
Under Rs 10,000
Top Choice: Honeywell Air Touch V5 (Rs 10,199)
The Honeywell Air Touch V5 could be one of the strongest value options in this price range. Its CADR is rated at about 380 m³/h and it covers roughly 55 m² (589 sq.ft). It uses a 4-stage system with True HEPA H13 filtration and activated carbon. It also supports Wi-Fi, Alexa and has a touch-panel for AQI data, which is rare at this price. Honeywell lists noise as low as 22 dB on its quiet setting. Filter life is said to be about 9,000 hours (about two years), and replacement filters cost around Rs 2,500. That gives it a low yearly running cost. The V5 could be ideal for users wanting big-room coverage and smart features without spending too much.
Runner-Up: Levoit Core 300 (Rs 10,999)
The Levoit Core 300 is a compact purifier aimed at small bedrooms or nurseries. It uses a 3-stage system with H13 True HEPA. CADR is listed at about 240 m³/h, and coverage is rated for around 219 sq.ft. Its QuietKEAP system is said to bring noise down to 24 dB in sleep mode. There is no app control, but it offers a timer, simple touch controls and an optional night light. Replacement filters last about 6–12 months and cost around Rs 3,000. It may not clean as quickly as the Honeywell V5, but its small size and quiet performance could suit smaller spaces.
Each price tier shows there is always a trade-off between upfront price, purification power and long-term filter cost. High-end models like the Dyson HP12 or BP02 bring design and comfort features, but mid-range units such as the Philips AC4221 or Coway Storm may deliver stronger CADR for less. And in the budget bracket, models like the Honeywell V5 show that good H13 filtration can still be affordable.
I hope this guide, based on claimed CADR figures, filter specs, noise levels, power use and smart-feature support, helps you pick an air purifier that suits both your budget and your room size. Breathe easy and keep reading Digit.in for similar guides and stories.
