Clean indoor air isn't just about comfort. It's about your family's health and wellbeing. With Australians spending up to 90% of their time indoors, choosing the right air purifier can make a real difference to allergies, sleep quality and overall respiratory health. This guide will walk you through everything you need to know to pick the perfect Levoit air purifier for your home and lifestyle.
6 Things To Check Before You Buy An Air Purifier
Room Size And Coverage (CADR Explained)
The most important factor when choosing any air purifier is making sure it can handle your room size. Levoit measures this using CADR (Clean Air Delivery Rate), which tells you how much clean air the purifier delivers per minute.
For best results, choose a purifier that can clean your room's air at least 2-3 times per hour. If you have a 20m² room, look for a model with CADR ratings that can handle 40-60m² of coverage. This ensures the air stays consistently clean, even when doors are opened or new pollutants enter the space.
Filter Type: True HEPA vs Others
True HEPA filters are the gold standard for air purification. They capture 99.97% of particles as small as 0.3 microns, including dust mites, pollen, pet dander and even some bacteria and viruses.
Many Levoit models combine True HEPA with activated carbon filters. The carbon layer tackles odours, smoke and chemical vapours that HEPA filters can't handle. This combination is particularly valuable for pet owners, smokers or anyone living near busy roads.
Noise, Energy and Placement Tips
Nobody wants an air purifier that sounds like a jet engine, especially in bedrooms. Check the noise levels, anything under 25dB on the lowest setting is virtually silent. Most Levoit models offer sleep modes that automatically reduce fan speed and noise levels during night hours.
Energy efficiency matters too. Look for models with low wattage consumption, especially if you plan to run the purifier 24/7. Placement is crucial. Keep purifiers at least 30cm away from walls and avoid corners where airflow can be restricted.
Smart Features, App and Scheduling
Modern Levoit air purifiers offer smartphone apps that let you monitor air quality, schedule cleaning cycles and adjust settings remotely. Some models display real time air quality readings with colour coded indicators, so you can see exactly when pollution levels spike.
Auto mode is particularly useful. The purifier automatically adjusts fan speed based on detected air quality. This saves energy while ensuring your air stays clean without constant manual adjustments.
Maintenance and Replacement Filters
Factor in ongoing costs when making your decision. HEPA filters typically need replacement every 6-8 months, while carbon filters may need changing every 3-6 month, depending on usage.
Pre filters can often be vacuumed clean, extending the life of your main filters. Check Tech Sales Online accessories for genuine replacement filters.
Warranty and local support
Buying from an authorised retailer ensures you get full manufacturer warranty coverage and local support. This matters when you need filter replacements, technical help or warranty claims. Avoid grey imports that may not be covered by Australian warranty terms.
