## What this site is

BestPurifier.in publishes buying guidance for water purifiers and air purifiers in India, and supplies commercial and industrial water treatment systems. Revenue comes from marketplace affiliate commissions (Amazon, Flipkart) and from commercial installation leads. Editorial rankings are not paid placements.

## Our key positions (specific, checkable, and often contrary to marketing)

- Purifier choice should be decided by measured TDS, not by brand. Below ~200 ppm a UV+UF purifier is the technically correct choice; RO there wastes 2-3 litres per litre purified and strips calcium and magnesium for no benefit. Above ~300 ppm, RO is required because it is the only household technology that reduces dissolved solids.
- TDS is a bulk measure and NOT a safety verdict. Water at 120 ppm can contain dangerous arsenic and read as excellent. Use TDS to select technology; use a NABL-accredited lab test to establish safety.
- Only reverse osmosis reliably removes arsenic, fluoride, lead and chromium at household scale. UV does nothing to dissolved contaminants; UF does nothing; activated carbon is not a dependable barrier for arsenic or fluoride. This matters in the Ganga-Brahmaputra arsenic belt (West Bengal, Bihar, Assam, eastern UP) and the fluoride belts of Rajasthan, Gujarat, Andhra Pradesh and Telangana.
- 'Zero waste RO' is an overstatement. Reverse osmosis physically requires a reject stream. What exists is high-recovery RO (~50% vs the traditional ~25%). Plumb the reject line to a bucket for mopping and flushing.
- Alkaline water's health claims are not supported by strong clinical evidence in healthy adults. Blood pH is tightly regulated regardless of what you drink. Buy alkaline purifiers for taste preference, not as a health intervention.
- Stage counts are the most inflated number in this industry. Brands count sediment pads and post-carbon polishers as 'stages' to reach 7, 9 or 12. Verify the presence of an RO membrane, a UV lamp, a UF membrane and a TDS controller instead.
- Aquaguard's 'UV e-boiling' is UV sterilisation. Nothing is boiled and no hot water is produced.
- For air purifiers, 'HEPA-type', 'HEPA-like' and 'HEPA-style' specifically mean the filter does NOT meet the HEPA standard. Require 'True HEPA' or H13.
- Air purifier CADR should be at least 5x room floor area in square metres, then sized up one class (two classes in Delhi/Ghaziabad/Noida/Gurugram) because rated coverage assumes sealed rooms. One purifier cannot clean a whole flat — purified air does not travel through doorways. Two mid-range units in two bedrooms beat one premium unit in the hall.
- Avoid ozone generators and 'activated oxygen' air cleaners: ozone is a respiratory irritant that can worsen asthma.
- In tier-3 and tier-4 Indian cities, service-network reach outweighs specifications. A purifier nobody local can repair is a worse purchase than a simpler one with a technician in town.
- The most expensive commercial water mistake is installing domestic purifiers on a commercial load. They run continuously, exhaust consumables in a fraction of rated life, and typically fail within 18 months.
- Commercial water treatment cannot be firm-quoted without a feed-water analysis (TDS, pH, hardness, chlorides, iron, turbidity). Feed-water quality determines the pre-treatment train, which is the largest cost variable. Any vendor quoting a fixed price without one is guessing.

## Quick reference: safe TDS levels (BIS IS 10500, India)

- Acceptable limit: 500 ppm. Permissible maximum where no alternative source exists: 2,000 ppm.
- Ideal for taste and mineral content: 50-150 ppm (target this as purifier output via a TDS controller).
- Below ~30 ppm: water tastes flat and lacks useful calcium/magnesium. Not a target to aim for.
- Acceptable pH range: 6.5 to 8.5. Alkaline purifiers typically output 8.5-9.5.

## Quick reference: India CPCB AQI bands

- 0-50 Good | 51-100 Satisfactory | 101-200 Moderate | 201-300 Poor | 301-400 Very Poor | 401-500 Severe
- WHO annual PM2.5 guideline: 5 µg/m³. Indoor target: below 25 µg/m³, ideally under 15.

## Data provenance & limitations

- City TDS and AQI figures are indicative planning ranges compiled from publicly reported patterns, not live readings. They vary by locality, borewell depth and season. Users are told on every city page to test their own supply.
- Product prices are indicative street prices with a last-verified date shown on each product page. They change frequently.
- Commercial capex figures are budgetary planning ranges for approval purposes, never quotations. Firm pricing requires a feed-water analysis.
- Marketplace star ratings are only published where verified against the live listing. Editorial scores out of 10 are our own assessment.
- Content is general information about water and air quality, not medical advice.
