Cuisinart CAP-500 Air Purifier (White, Medium Room)

How often do I need to replace the HEPA filters?

The H13 HEPA filters are rated for 2500 hours of operation, which typically equals 3-4 months of continuous use. The unit includes a filter replacement indicator that alerts you when it's time to change them. However, if you run the purifier only during certain hours, the filters will last proportionally longer. The washable metal pre-filters help extend HEPA filter life by capturing larger particles first.

What room sizes work best with this air purifier?

The CAP-500 is designed for rooms up to 500 square feet, where it provides 2 complete air changes per hour. For maximum effectiveness, use it in rooms up to 250 square feet where it delivers 4 air changes hourly. Smaller rooms like bedrooms, home offices, or kitchens are ideal. The 250 CADR rating means it can handle moderate to heavy pollution levels in these spaces.

Can this unit remove cooking odours and pet smells?

Yes, the dual active carbon filters specifically target odours, cooking smells, pet odours and volatile organic compounds (VOCs). The carbon filtration works alongside the HEPA filters to capture both particles and gases. The 2-sided air intake increases the contact time with carbon filters, improving odour removal effectiveness compared to single-intake designs.

How loud is this air purifier during operation?

The CAP-500 operates with three speed settings, allowing you to balance noise levels with purification power. The lowest setting runs quietly enough for bedroom use, whilst higher speeds provide maximum air cleaning for heavily polluted environments. The touchscreen controls let you adjust speed based on your current needs and noise tolerance.

Do I need to buy special replacement filters?

Yes, you'll need genuine Cuisinart replacement filters to maintain the 99.9% particle capture efficiency. The unit requires two H13 HEPA filters and two active carbon filters when replacement time comes. However, the metal pre-filters are permanent and washable, so you never need to replace them. This reduces long-term operating costs compared to units requiring disposable pre-filters.

Where should I position this air purifier for best results?

Place the unit on a stable surface with at least 15cm clearance on both sides for proper air intake. Avoid corners or enclosed spaces that restrict airflow. Central room placement works best, but near pollution sources like litter boxes or cooking areas also proves effective. The 2-sided intake design offers more placement flexibility than traditional single-intake models.

Will this help with allergies and asthma symptoms?

The H13 HEPA filters capture common allergens including pollen, dust mites, pet dander and mould spores down to 0.1 microns. This level of filtration removes particles that typically trigger allergic reactions and respiratory symptoms. The continuous air cycling helps maintain consistently clean air, which many users find beneficial for managing allergy and asthma symptoms.

How much electricity does this air purifier consume?

The CAP-500 uses 40 watts of power, making it energy-efficient for continuous operation. Running 24/7 costs approximately £3-4 monthly based on average UK electricity rates. The three speed settings allow you to reduce power consumption when maximum purification isn't needed. This low energy usage makes it practical to run continuously for optimal air quality.
