Puroair HEPA 14 Air Purifier

How often should I replace the HEPA 14 filter?

Replace the HEPA 14 filter every 6-12 months depending on usage and air quality conditions. The built-in filter life indicator will alert you when replacement is needed. Heavy use in polluted environments may require more frequent changes, whilst light use in clean areas can extend filter life. The pre-filter should be cleaned monthly and replaced every 3 months to maintain optimal performance.

What room size does this air purifier effectively cover?

This unit effectively purifies rooms up to 40 square metres with 5 complete air changes per hour. For smaller rooms under 20 square metres, it provides even more frequent air changes for superior cleaning. The 360-degree air intake and powerful motor ensure even large rooms receive thorough air purification. Room layout and ceiling height can affect coverage, with open plan spaces requiring positioning for optimal airflow.

How loud is the air purifier during operation?

On the lowest speed setting, noise levels stay below 25dB, quieter than a whisper and suitable for bedrooms during sleep. Medium speed operates at approximately 35dB, similar to a quiet library. Maximum speed reaches 50dB, comparable to light rainfall. The advanced motor design and sound dampening materials minimise operational noise whilst maintaining powerful air cleaning performance.

Does this remove cigarette smoke and cooking odours?

Yes, the HEPA 14 filter combined with activated carbon layer effectively removes smoke particles and cooking odours. The medical-grade filtration captures smoke particles down to 0.1 microns whilst the carbon layer absorbs odour-causing gases. However, for heavy smoke environments, consider placing the unit closer to the source and running on higher speeds for optimal results.

Can I run this air purifier continuously 24/7?

Absolutely, this unit is designed for continuous 24/7 operation. The energy-efficient motor consumes minimal electricity whilst the quiet operation won't disturb sleep or daily activities. Continuous running actually improves air quality by maintaining consistent filtration. The auto mode feature adjusts speed based on air quality, providing optimal cleaning whilst conserving energy during cleaner periods.

What types of particles does the HEPA 14 filter capture?

The HEPA 14 filter captures 99.995% of particles including dust mites, pollen, pet dander, bacteria, viruses, mould spores and ultrafine particles down to 0.1 microns. This exceeds standard HEPA 13 filters which only capture particles down to 0.3 microns. The medical-grade filtration makes it particularly effective for people with allergies, asthma or those requiring cleaner air for health reasons.

How much electricity does this air purifier use?

Power consumption ranges from 8W on lowest speed to 45W on maximum speed, with typical usage around 25W. This equals approximately 2-4 pence per day to run continuously, making it very economical. The Energy Star certified motor and efficient design keep running costs low whilst maintaining powerful air cleaning performance. Annual electricity costs typically range from £15-30 depending on usage patterns.

Is assembly required and how difficult is setup?

Minimal assembly is required - simply remove packaging, install the filters and plug in. The process takes under 5 minutes with clear instructions provided. Filters come pre-installed in protective packaging that must be removed before first use. The intuitive control panel and automatic features mean no complex programming is needed. Simply select your preferred speed or use auto mode for hands-free operation.
