best air purifiers featured

Air purifiers have become a must-have in many UK homes, owing to their ability to remove airborne contaminants and allergens, making the indoor environment cleaner and healthier. For those who suffer from allergies, asthma or other respiratory issues, a good air purifier can work wonders. Air purifiers come in various shapes, sizes and features, but they all have one primary goal: to improve the air quality of your living space.

In the UK, where outdoor air pollution can sometimes be a concern, having an air purifier ensures that you are breathing cleaner and fresher air inside your home. The effectiveness of an air purifier is determined by its coverage area, filter quality, and the amount of air it can clean per hour. With advancements in technology, many air purifiers in the market also come equipped with additional features, like mobile app connectivity, filter replacement indicators, and silent operation modes.

When choosing the best air purifier for your needs, it’s essential to consider factors like room size, filter replacement costs, noise levels, and energy consumption. It’s also crucial to look for air purifiers with a high Clean Air Delivery Rate (CADR), as this indicates how efficiently the purifier can clean the air in a given space. Additionally, always opt for purifiers with HEPA filters, as they can effectively capture particles as small as 0.3 microns.

After weighing all these factors, I spent several hours researching and testing various air purifiers available in the UK market to help you find the ideal model that caters to your requirements and keeps your home’s air fresh and clean.

Lastly, depending on usage, the filter may need to be replaced frequently.

Despite these minor flaws, the Levoit Core 300 Air Purifier remains an excellent choice for those struggling with allergens, pet hair, and poor air quality. The benefits provided by its powerful and efficient air cleaning technology, as well as its quiet operation and customization options, outweigh the limitations.

Having the ability to control the device using Alexa, Google Assistant, or the VeSync app is a game-changer. I can check indoor/outdoor air quality and filter life on the go. The app itself could have better instructions, but once you find the features, it works perfectly fine.

One thing I love about the Levoit Core 300S is the sensor and auto mode. The AirSight Plus Technology laser sensor monitors air quality in real time, providing information through colour-coded halos. In automatic mode, the purifier adjusts wind speed according to air quality, which makes it quite intuitive and smart.

A minor issue I encountered was that the purifier didn’t seem to detect certain volatile organic compounds (VOCs) from my kitchen appliances. However, it effectively absorbs odours, smoke, and other allergens in the room.

It would have been great if there was an all-in-one solution for air purification and dehumidifying, but the Levoit Core 300S still works brilliantly as an air purifier. Overall, I would highly recommend this air purifier for those seeking better indoor air quality, reduced allergy symptoms, and smart control options.

Compared with the Levoit Core 300, the Levoit Smart Core 300S takes air purification to the next level with its smart features and enhanced functionality.

Our score: 4.5

Initially, I was sceptical about this purifier, but upon using it, I could immediately feel the difference in air quality. As a hay fever sufferer, I often struggle with pollen, dust, and other allergens. However, this air purifier did wonders in eliminating them!

The various settings, including a sleep mode, made it easy for me to use it throughout the day and night without feeling overly disturbed. It’s particularly fantastic during peak pollen season, as I no longer wake up in the middle of the night struggling to breathe.

One downside was the need to replace the HEPA filter every six months, but it wouldn’t be a dealbreaker considering the positive impact it had on my life. Additionally, I didn’t find the ioniser function particularly useful for me, but I understand it might be beneficial for others. The limited speed setting choices could be a minor concern for some users as well.

Compared with the Levoit Core 300, the Silentnight with HEPA & Carbon Filters offers a different set of features that may appeal to specific needs. While the Levoit Core 300 boasts Vortexair Purify Technology and customizable replacement filters, the Silentnight model stands out with its focus on allergen removal and odor control. Equipped with a HEPA filter and an activated carbon filter, it effectively captures airborne allergens as small as 0.3 microns and neutralizes household odors from pets, cooking, and smoking.

The Silentnight air purifier also includes a timer function, sleep mode for quieter operation, and an ionizer feature to aid the air purification process. Its compact design and touch control method provide ease of use in various environments. If your primary concern is allergen reduction and odor elimination, the Silentnight with HEPA & Carbon Filters presents itself as a suitable choice alongside the Levoit Core 300.

Compared with the Levoit Core 300, the Afloia for Home Bedroom offers a compact and efficient solution for air purification in smaller spaces. While the Levoit Core 300 is equipped with Vortexair Purify Technology and a variety of replacement filters, the Afloia model focuses on effective air cleaning with its HEPA filter.

The Afloia air purifier is designed to purify the air 4 times per hour in rooms up to 1076 ft², making it suitable for bedrooms, living rooms, smoking rooms, and kitchens.

This combination ensures that my air stays clean and fresh.

The only downsides I found were its size and noise at higher fan speeds. While it’s a bit bulky, it doesn’t take away from its functionality. And though the sleep mode is whisper-quiet, I do notice some noise when using higher fan speeds.

Do keep in mind that the coverage area is relatively small, so this air purifier works best in bedrooms or smaller rooms.

One of the standout features is the quiet sleep mode – when running on this setting, the noise level is as low as 28 decibels, so it doesn’t disturb my rest. However, the filters do need to be replaced every 6-8 months, so plan accordingly to maintain the air purifier’s optimal performance.

Alternatives to Air Purifiers

If you are looking for an alternative to using an air purifier, there are a few options available to help improve indoor air quality. One alternative is to improve ventilation in your home by opening windows or using exhaust fans to bring in fresh outdoor air and remove pollutants. Additionally, using natural methods such as keeping indoor plants can help in filtering the air and reducing certain airborne toxins. Regularly cleaning and dusting your home, using natural cleaning products, and maintaining a healthy humidity level can also contribute to better indoor air quality. However, it’s important to note that these alternatives may not be as effective as air purifiers in removing fine particles, allergens, and other pollutants from the air. The choice of an alternative ultimately depends on the specific needs and circumstances of each individual.

Consider Room Size

When choosing the best air purifier for my needs, I first consider the room size that I plan to use it in. Most air purifiers mention their room size capability in square metres (m²), which helps me find the one best suited for my room. For example, a small air purifier may be suitable for a 10m² room, while a larger model might cater to spaces up to 30m² or more.

Filter Types

There are various filter types available, each with unique benefits and applications. The most common filter types I consider are:

  • HEPA (High-Efficiency Particulate Air) filters: These filters are highly efficient at capturing small airborne particles, making them great for allergy sufferers.
  • Activated carbon filters: These filters help to remove odours and volatile organic compounds (VOCs) from the air.
  • Pre-filters: These filters help to capture larger particles like dust, pet hair, and lint, extending the life of the main filter.

Noise Levels

Since I want to have a comfortable home environment, it’s important for me to check the noise levels of the air purifier. They are generally measured in decibels (dB) and can vary depending on the device’s settings. A noise level of around 50dB would be considered quiet and a level of 70dB or higher may be intrusive.

Energy Efficiency

Energy consumption is another factor I always take into account. Most air purifiers display their power usage in watts (W). Choosing an energy-efficient purifier can help me save on electricity costs over time.

Additional Features

Lastly, I consider any additional features that may benefit my needs, such as:

  • Smart sensors: These help monitor and adjust air purification settings based on real-time air quality readings.
  • Timer functions: Timers allow me to set the air purifier to operate at certain times of day, conserving energy and ensuring clean air when I need it.
  • Wi-Fi connectivity and app control: Some air purifiers can be controlled through smartphone apps for more effortless management and monitoring of the purification processes.

By considering these aspects, I ensure I am selecting the best air purifier for my unique requirements.

Conclusion

I’ve looked at various air purifiers available in the UK, and it’s clear that there are plenty of excellent options out there. While each model has its unique features and benefits, there are a few key factors to consider when choosing the best air purifier for your needs.

Firstly, the type of filter used is crucial. HEPA filters are the most effective, capturing up to 99.97% of airborne particles as small as 0.3 microns. Other filters, such as carbon filters or ionizers, can also help reduce odours and neutralise harmful gases. When choosing an air purifier, make sure it has a combination of filters to tackle various pollutants efficiently.

Secondly, the room size it can cover is essential. Make sure to check the recommended coverage area, and choose a purifier that can effectively clean the air in your desired space. It might be a good idea to opt for an air purifier with slightly higher coverage than needed, as this ensures it will work efficiently even as the filters age.

A few other factors to consider include:

  • Noise level: look for a purifier with low noise levels, especially if it will be used in a bedroom or office.
  • Energy consumption: select energy-efficient models that won’t dramatically increase your electricity bill.
  • Maintenance: it’s important to choose an easy-to-maintain purifier with filters that you need to change only a few times a year. Moreover, it’s not a bad idea to check the availability and cost of replacement filters while making your choice.

In conclusion, finding the best air purifier for you can make a real difference in your indoor air quality and ultimately, your wellbeing. By considering the key factors above and comparing the top options in the UK market, you’ll be well-equipped to make the right choice for your specific needs. Happy breathing!
