Top 10 things to check before buying an air purification system

1. Independent test results, not just bold claims

Look for evidence that any performance data comes from independent testing, not just in-house trials. Full test reports should be available if needed.

2. Real testing on the actual product range

General statements like “UV kills viruses” do not prove effectiveness. Has the product range itself been tested for air purification?

3. Realistic testing conditions

Testing should reflect real-world use, with appropriate controls. Extended exposure times or lack of untreated comparisons can mislead.

4. Credible laboratory standards

Pathogen testing requires specialist labs with proper controls. Check that testing has been conducted in recognised or accredited facilities.

5. Safe for occupied areas (if that is the goal)

Some systems can only operate in unoccupied spaces. Confirm whether the technology is suitable and certified for use around people.

6. Effective performance beyond the unit itself

Products that rely on air passing through the unit may only treat a fraction of the room air. Ask how the system ensures wider coverage.

7. A range of products, not a one-size-fits-all approach

A product that works in a washroom may not suit an office, school, or warehouse. Suppliers should offer solutions tailored to different environments and challenges.

8. Experience and real-world use

Look for suppliers with a track record of use in your sector. Broad or vague experience claims may signal a newer entrant to the market.

9. Beware of unrealistic claims

No product can guarantee complete protection in all situations. Air purification systems should be part of a wider hygiene strategy, not a standalone solution. Reputable suppliers will clarify what their system can achieve and what still depends on cleaning, maintenance, and overall site conditions.

10. Clear answers to your questions

Reliable suppliers will explain test results, product safety, and expected performance without hesitation. If answers seem vague, keep asking or look elsewhere.
