10 Best Air Purifiers

The Philips Air Purifier 4200 Series is designed to cover large rooms up to 156 m², making it a strong choice for bigger living spaces or open-plan homes. Its CADR of 600 m³/h means it can clean the air in a 20 m² room in under 5 minutes, which is quite efficient. The purifier uses a 4-layer HEPA NanoProtect filter combined with double active carbon filters, capturing tiny particles as small as 0.003 microns, including pollen, dust, pet dander, viruses, and bacteria. This makes it suitable for allergy sufferers and those wanting to reduce airborne viruses. The device is also ECARF certified, confirming its effectiveness against common allergens.

Noise levels are impressively low thanks to SilentWings technology, with sound as quiet as 15 dB(A) at low speeds, so it won't disturb your daily activities or sleep. Energy use is modest at 54 watts, which keeps running costs down compared to some other models. The purifier can be controlled remotely via the Air+ app, allowing you to monitor air quality and adjust settings from your phone, a handy feature for tech-friendly users. Maintenance is user-friendly with a smart indicator that alerts you when filter changes are needed, and filters last up to a year depending on usage.

On the downside, while it excels in many areas, the purifier weighs 6.54 kg and has a fairly tall design (52 cm), which might take up noticeable space in smaller rooms. Also, being a premium model, it may come at a higher price point than basic purifiers. This makes it a highly recommended option for those seeking strong filtration, quiet operation, and smart features, especially in larger Australian homes.

The Philips 1000i Series Air Purifier is designed for medium to large rooms, effectively covering up to 78 square meters with a strong Clean Air Delivery Rate of 300 m³/h. Its three-layer filtration system combines a NanoProtect HEPA filter, activated carbon, and a pre-filter, capturing 99.97% of tiny particles, including allergens and odors. This makes it a solid choice for people wanting cleaner air from dust, pollen, smoke, or pet dander.

One of its notable strengths is the smart air quality sensor that checks the air 1,000 times per second and adjusts the purifier's speed automatically. You can monitor and control it easily through the Air+ app or voice assistants like Alexa and Google Home, adding convenience and modern connectivity. The purifier runs quietly on its lowest setting (as low as 15 dB), which is great for bedrooms or offices, though the maximum noise level can reach up to 70 dB, which might be noticeable in quiet environments.

Maintenance is straightforward, with an energy-efficient filter designed to last around 12 months and smart alerts to remind you when it's time to replace it. While the device is slightly bulky in size, its efficient cleaning speed—purifying a 20 m² room in just 10 minutes—is impressive. Some users might find the higher noise level at full power a bit disruptive, but the Philips 1000i balances effective purification, smart features, and user-friendly design, making it suitable for those who want reliable air cleaning with modern controls and low maintenance.

The Philips Air Purifier Smart 1000i is a solid choice for anyone looking to improve air quality in medium to large rooms, covering up to 78 square meters. Its 3-layer HEPA filtration captures 99.97% of very small particles, including pollen, dust, pet dander, and smoke, making it especially helpful for people with allergies or asthma. The purifier works efficiently with a high Clean Air Delivery Rate (CADR) of 300 m³/h, meaning it can clean a smaller room (20 m²) quite quickly, in under 10 minutes.

One of its standout features is its quiet operation; at its lowest setting, it runs almost silently (15 dB), which is great for bedrooms or offices. It’s also energy-efficient, using less power than a typical light bulb. The smart connectivity via the Air+ app lets you monitor air quality in real time and control the device remotely, adding convenience. The built-in sensor automatically adjusts the fan speed based on detected pollution levels, ensuring effective cleaning without wasting energy.

On the downside, the unit is relatively large and weighs over 5 kilograms, which might make it less portable compared to smaller models. The purifier is well-made, backed by Philips’ long experience and extensive testing, and is allergy-certified, giving extra confidence in its performance. This model suits those who want a reliable, tech-friendly air purifier that balances power and quiet operation for larger indoor spaces.
