FAQs

Do air purifiers help with allergies at night?

Yes. A true HEPA purifier removes 99.97% of airborne allergens including dust mites, pollen, and pet dander — the main triggers for night-time symptoms.

How quiet does a bedroom air purifier need to be?

Under 30dB on night mode is ideal — that is quieter than a whisper. Most people cannot hear anything below 25dB.

Should I run an air purifier all night?

Yes. Continuous operation keeps allergen levels low throughout the night. Energy costs are minimal — around 1–3p per night.
