🌬️ Air passes through three filters in sequence — each removing a different category of pollutant
Stage 1 — Pre-Filter
Traps large particles: hair, dust, pet dander, lint. Washable + reusable. Protects downstream filters from clogging.
Stage 2 — Deodorisation Filter
Activated carbon removes VOCs, smoke, cooking odours, gases, formaldehyde, chemical fumes. Neutralises smells.
Stage 3 — Anti-Virus Green True HEPA H13
99.999% removal @ PM 0.01 µm — viruses, bacteria, PM 2.5, PM 0.1, allergens, mould spores, pollen.

Anti-Virus Green True HEPA H13 — what 99.999% @ PM 0.01 µm means for Delhi NCR air
HEPA (High-Efficiency Particulate Air) filters are classified by efficiency tiers — H10 (85%), H11 (95%), H12 (99.5%), H13 (99.97% @ 0.3 µm), H14 (99.995% @ 0.3 µm). Standard HEPA air purifiers sold in India use H11 or H12 filters — adequate for dust and pollen but less effective for the smallest particles. The Coway AirMega 250's Anti-Virus Green True HEPA H13 specification adds two critical upgrades. First, the efficiency tier: H13 at 99.97% vs H11's 95% at 0.3 µm means that for every 10,000 particles at 0.3 µm entering the filter, H13 allows 3 to pass vs H11's 500 — nearly 167× more particles blocked at this size. Second, the particle size rating: standard HEPA specifications are tested at 0.3 µm (the most penetrating particle size for fibrous filter media). The Coway's "PM 0.01 µm" specification and 99.999% efficiency rating refers to its performance at 0.01 micron — a particle size relevant to viruses (influenza: 0.08–0.12 µm, coronavirus: 0.06–0.14 µm, rhinovirus: 0.02–0.03 µm) and ultrafine particulates from combustion and vehicle exhaust. Delhi NCR's air quality challenge is specifically relevant here: the city's PM 2.5 annual average regularly exceeds WHO guidelines by 10–15×, and during Diwali or crop-burning periods, AQI values of 400–500+ carry significant ultrafine particle loads from combustion that standard H11 filters pass at measurable rates. The "Anti-Virus" designation reflects testing against specific viral particles at the 99.999% efficiency level — a standard above the typical H13 specification. The "Green" designation is Coway's branding for their enhanced anti-microbial filter coating that reduces bacterial growth within the filter media itself during extended use.
930 sq ft coverage — sizing the AirMega 250 to Delhi NCR apartments and offices
Air purifier coverage area is calculated based on CADR (Clean Air Delivery Rate) — the volume of clean air the purifier delivers per hour, divided by the room volume to determine how many times per hour the room air is cycled through the filter. The standard recommendation is 4–5 air changes per hour (ACH) for adequate purification in a polluted environment; 2 ACH for maintenance purification in already-clean conditions. The Coway AirMega 250's 930 sq ft specification assumes a standard 8-foot ceiling height (approximately 86 m³ volume for a 930 sq ft room) at approximately 4 ACH — appropriate for Delhi NCR conditions during moderate pollution days. In practical Delhi terms: a standard 2BHK apartment's combined living + dining room (typically 350–450 sq ft) is well within the AirMega 250's coverage capacity — the purifier handles the full open-plan area with headroom for higher ACH during peak pollution events. A 3BHK master bedroom suite (typically 200–280 sq ft) can be purified by the AirMega 250 at 6–8 ACH, providing very fast air cleaning response to sudden pollution events (cooking fumes entering from an adjacent open-plan kitchen, or outdoor pollution spike from a vehicle below the window). For office use: a standard Indian office cabin (150–200 sq ft for a senior manager's private cabin) is purified at high ACH rates, while an open-plan office pod of 600–700 sq ft is within comfortable coverage range. The 930 sq ft maximum is the rated large-room performance at 4 ACH with clean filters — as filters age toward their 8500-hour replacement cycle, CADR decreases slightly, effectively reducing the comfortable coverage area over time.
22 dB operation + Night Mode — the acoustic engineering that makes bedroom air purification practical
22 decibels is below the threshold of audibility for most adults in a quiet environment — for reference, normal breathing is approximately 10 dB, a library environment is 30 dB, and a quiet bedroom at night is approximately 30–35 dB. At 22 dB, the Coway AirMega 250 operating at minimum speed in a bedroom at night is inaudible against the background ambient noise of the room — ceiling fans (40–50 dB), distant traffic (35–45 dB), and HVAC hum (30–40 dB) all produce more sound than the purifier. This matters specifically for air purifiers because the most important room for continuous air purification is the bedroom — adults spend 7–8 hours per night breathing bedroom air directly, and children spend 9–11 hours. A purifier that is audible in a quiet bedroom either forces the user to turn it off at night (defeating the purpose during the longest continuous exposure period) or disrupts sleep quality through continuous low-level noise stress. The Coway's Night Mode combines the 22 dB minimum fan speed with an additional feature: the AQI indicator LEDs are automatically turned off in darkness. This addresses the sleep disruption caused by the LED indicator lights of most air purifiers — red or amber AQI alerts in a dark bedroom create visual stimulation that disrupts sleep even when the purifier is acoustically quiet. Night Mode detects ambient light reduction and simultaneously minimises motor speed (quietest operation) and turns off all indicator LEDs, creating a genuinely unobtrusive sleep environment while maintaining air purification throughout the night.
8500-hour filter life + Delhi NCR pollution context — real maintenance costs
The Coway AirMega 250's HEPA H13 filter is rated for 8500 operational hours — at 12 hours of daily use (a typical household pattern of daytime + overnight operation), this equals approximately 708 days (nearly 2 years) of filter life. At 24 hours/day continuous operation (common in high-pollution households during Delhi's October–February pollution season), the filter life reduces to approximately 354 days (approximately 1 year). Delhi NCR's air quality profile makes filter life calculation particularly important: during October–February (the peak pollution season when AQI regularly exceeds 200–400), a purifier running on Smart Auto mode operates at higher average fan speeds than during cleaner months, which does not directly reduce filter life (HEPA filter life is primarily determined by particle loading, not fan speed) but does mean more air volume is processed per day and more particles are captured per hour. The pre-filter's washable design is specifically important for Delhi's dust loading: the pre-filter captures large particles (hair, visible dust, pet dander) that would otherwise rapidly clog the more expensive HEPA filter. Monthly washing of the pre-filter (a 2-minute process under running water) extends the HEPA filter's effective life by preventing premature loading from large particles. The deodorisation filter (activated carbon) typically needs replacement at 6–12 month intervals in kitchens or cooking-adjacent spaces where VOC loading is high — in a bedroom or office with minimal cooking-related air pollution, the carbon filter approaches the same 8500-hour lifespan as the HEPA. Coway India's filter replacement indicator on the touch panel removes the guesswork — a sensor estimates remaining filter life based on operational hours and fan speed history, alerting when replacement is due.
