As of 13 August 2026, AI can only partly choose an air purifier for your business premises.

What to actually do

1. Hand it to a person

   The route this page recommends

   A person who owns the outcome does this end to end, worth it when the failure is dear.

2. Use a tool built for this

   Second choice

3. Do it yourself

   The distant third

   A chat interface, chat-fluent skill, and roughly 30 minutes until you can act on the result.

   How to actually do it

   1. Open a site plan, lease information or measuring notes and record each room's length, width, ceiling height, normal occupancy, busiest occupancy and opening hours.
   2. Ask your facilities or maintenance contact for the existing ventilation, HVAC, power-supply and fire-safety information, and mark anything unknown rather than guessing.
   3. Gather your purchase budget, acceptable noise level, placement restrictions, main air-quality concern and any required delivery date.
   4. Paste those details into the prompt and ask the model to shortlist current UK-available products with a source link for each material claim.
   5. Open the manufacturer pages and manuals for every shortlisted model, then compare the drafted model numbers, airflow, noise, power, filter and warranty details against those documents.
   6. Send the shortlist and the premises constraints to the person responsible for facilities, health and safety or procurement, and ask them to confirm ventilation, electrical, placement and maintenance requirements before ordering.
   7. Choose the model only after recording the confirmed specifications, supplier price, replacement-filter route and person responsible for maintenance in your purchasing record.

   Prompt

   Help me choose a commercial air purifier for my UK business premises. Do not make up specifications, prices, certifications, availability or performance claims. Use current manufacturer or retailer sources and give a source link for every material claim.
   
   Premises:
   - Business type: [business type]
   - Location in the UK: [town or region]
   - Rooms or zones to cover, with length, width and ceiling height: [details]
   - Number of people normally present and busiest occupancy: [details]
   - Opening hours: [details]
   - Existing ventilation or HVAC: [details or unknown]
   - Main concern: [dust, smoke, allergens, odours, particles, infection-control support, other]
   - Noise limits or quiet periods: [details]
   - Placement, power and drainage constraints: [details]
   - Purchase budget and ongoing running-cost limit: [details]
   - Required delivery date: [date]
   
   First, list the missing facts that could change the recommendation. Then research suitable models available in the UK and produce a shortlist of no more than five. For each model, give the exact model number, manufacturer, verified particle-filtration claims, stated room or airflow figures, noise levels, dimensions, power use, filter replacement information, warranty, current price if verified, retailer or manufacturer source, and any relevant certification or limitation. Separate manufacturer claims from your own comparison.
   
   Explain which models are unsuitable and why. Do not treat room coverage claims as proof that the purifier will solve an air-quality or health problem. Flag where a facilities manager, ventilation specialist, electrician or other qualified professional should check the premises before purchase. Finish with a provisional recommendation, the conditions that must be confirmed first, and a practical checklist for checking the chosen model before ordering.
