Best deals on air purifiers: FAQs
What size air purifier do I need for my room? It's important to choose an air purifier that's appropriately sized for your space. Look for the product's listed coverage area, usually given in square feet or metres. For larger rooms, consider purifiers with a higher Clean Air Delivery Rate (CADR), which indicates how quickly the purifier can clean the air in a specific volume.
How often should I replace the filter in an air purifier? The lifespan of an air purifier filter depends on the specific model and how often you use it. Many purifiers thoughtfully include filter indicators to let you know when it's time for a replacement. Generally, HEPA filters should be replaced every 6 to 12 months to maintain optimal performance.
Do air purifiers remove odours? Yes, many air purifiers are designed to combat odours as well as particles. Those equipped with activated carbon filters are particularly effective at removing common household odours, like smoke, pet smells, and cooking fumes, in addition to dust and allergens.
Are air purifiers noisy? Noise levels can vary between different air purifier models. However, many manufacturers understand the need for quiet operation, especially in bedrooms, and offer a sleep mode with significantly reduced noise levels. Checking the decibel rating in the product specifications can help you find quieter options.
Can air purifiers help with allergies? Absolutely. Air purifiers that feature HEPA filters are very effective at capturing airborne allergens such as pollen, dust mites, and pet dander. This can make a significant difference for individuals who suffer from allergies or asthma, creating a more comfortable and breathable environment.
