How the aqi0 Whole-Home Air Purifier Works

aqi0 supplies filtered outdoor air through a standalone whole-home air purifier. Technically, it is a positive-pressure fresh air system: an outdoor unit draws air through filters and supplies it indoors through its own intake and supply path.

This guide explains the equipment and the decisions we confirm with you before installation. The technical note is the detailed reference for installation, service, warranty and performance commitments.

Follow the air through the system

1. Outdoor intake: the location is assessed for nearby exhaust outlets, traffic sources, weather exposure and maintenance access.
2. Washable pre-filter: the first stage catches coarse debris before the fine-particle filter.
3. H13 HEPA filtration: the second stage filters fine particles from incoming air. Particle filtration is not a claim to remove every outdoor gas or odour.
4. Variable-speed EC fan: the fan supplies filtered air through the duct into the home.
5. Indoor diffuser and room connections: air distribution depends on the layout, door gaps and exit paths. Closed rooms with full threshold seals need particular attention.

The machine sits outdoors. Indoors, the duct ends at a diffuser; the standard arrangement does not require a separate supply duct to every room. aqi0 does not currently offer integration with an existing HVAC system.

How coverage is planned

One unit is specified for up to 2,000 sq ft of carpet area. Above that, or across multiple floors, we plan for two units and assess their positions. Ceiling height and room connections also matter.

The published figures are approximately 700 m³/h free-air airflow and 500 m³/h effective airflow in service. These are different rating conditions. An airflow figure divided by room volume gives a nominal air-change rate, not a guarantee that every part of the home is completely refreshed in that interval.

What installation requires

Before installation we confirm an external opening, the duct route, mounting, power and access for cleaning with you. The standard specification calls for a 10-inch circular opening and a nearby 6A power point. Toughened glass requires a replacement panel prepared by a specialist; it cannot be cut after tempering. Any site-specific work is discussed before installation.

Outdoor air also brings a temperature and moisture load. Discuss comfort during summer, winter and monsoon conditions alongside airflow. The system is not an air conditioner or dehumidifier.

Filter care and ownership cost

Clean the washable pre-filter every 7–10 days, following the care instructions. Allow washed material to dry before refitting. Do not wash the HEPA panels.

The system has three H13 panels. Under the annual care plan, one panel is replaced on rotation at each scheduled visit, alongside machine cleaning. Visits are approximately every 45 days during October–February, with the rest of the year’s schedule based on pollution load.

• System: ₹82,600, fully installed.
• Annual care plan: ₹14,750 per year.
• Replacement HEPA panel: ₹2,200 each outside the plan.
• Optional AQI/PM2.5 monitor: ₹4,000, sold separately; it is not a CO₂ monitor.

See pricing and the filter-care guide for details.

What is checked after installation?

Indoor PM2.5 is measured before operation and at commissioning. For a useful comparison, record the outdoor conditions, rooms, activities and equipment settings as well. The written commitment and remedy apply under the conditions in the technical note, including current filters and the home operating as designed.
