An air purifier can greatly benefit your home during the colder months, especially when it comes to promoting a healthier living environment. By removing indoor allergens and pollutants, it helps reduce allergy symptoms and respiratory issues that can be exacerbated during this season. We tend to keep our homes sealed, resulting in the buildup of pollutants and allergens over time. An efficient air purifier can assist in eliminating these issues. Some air purifiers may even help to eliminate viruses and bacteria, lowering the risk of illness, which is particularly relevant during the winter season when colds and the flu are prevalent. 

Air purifiers help improve the overall indoor air quality, ensuring that your home stays fresh and comfortable. They filter various airborne particles and pollutants such as dust, pollen, mould spores, bacteria, toxic fumes, odours, volatile organic compounds (VOCs) produced by household chemicals and products, and more, contributing to a cleaner and healthier home environment. In this article, we take a look at some of the Top Air Purifiers currently available at PB Tech! Before we dive in, these are some key factors to keep in mind when choosing one. 

How to choose an Air Purifier?

Room Size & CADR: The size of the room where the air purifier will be used is an important factor to ensure optimal performance. Measure the square footage of the room and ensure this fits the room coverage for the Air Purifier you are considering. You should also check the device's Clean Air Delivery Rate (CADR). CADR measures the device's ability to remove airborne particles (smoke, pollen, and dust) and can be matched with your room size to ensure effective filtration.

Filter Type: Different filters target different contaminants. Pre-filters capture larger particles, prolonging the life of the main HEPA filter. Activated carbon filters help reduce odors, smoke, and volatile organic compounds (VOCs). UV-C lights and filters with antimicrobial treatment destroy bacteria, viruses, and mold spores. High-Efficiency Particulate Air (HEPA) filters are essential for removing small particles such as pollen, pet dander, mold spores, and dust mites. Many Air Purifiers will include one or a combination of these; and others may include a unique filter created by the manufacturer. 

Maintenance and filter replacement: Proper maintenance prolongs the air purifier's life and ensures optimal performance. Consider models with easy-to-change filters, washable pre-filters, and filter replacement indicators. The filter's lifespan varies by type and usage; however, HEPA filters typically need replacement every 12-18 months, while activated carbon filters may need replacement every 3-6 months.

Noise Level: Since air purifiers may be running continuously, a quiet operation is preferable. Noise level is measured in decibels (dB). For bedrooms or living areas, look for devices with a dB rating below 50. Many purifiers have variable speed settings, enabling you to adjust the noise level according to your needs. Some will also have 'Night Mode' or similar, which will adjust settings to ensure you can sleep with ease. 

Extra Features: Depending on budget and preference, you can explore air purifiers with added functionality. Air quality sensors detect and display real-time air quality, while adjustable fan speeds give you enhanced control over noise, energy usage, and filtration. Temperature and humidity sensors will provide an overview of other contributors to a healthy home. Night modes, programmable timers, and Wi-Fi connectivity allow for more flexibility in operation, monitoring, and control.
