HEPA & Carbon Filter Effectiveness
When choosing an air purifier, it’s important to understand how well they filter out harmful particles. Let’s look at a few models to see how they compare in terms of HEPA and carbon filter efficiency.
The Blueair Blue Signature Air Purifier features seven-stage filtration, including HEPA silent technology. This helps it capture a variety of air pollutants effectively. It can clean areas up to 63 square meters and operates quietly, making it suitable for bedrooms or living rooms.
On the other hand, the Shark NeverChange5 Air Purifier HP150UK uses multiple filters, including a NanoSeal HEPA layer and activated carbon.

Coverage Area & CADR Rating
When choosing an air purifier, it’s important to look at its coverage area and Clean Air Delivery Rate (CADR) rating. These factors tell you how large a space the purifier can effectively clean and how fast it can do it. Let’s compare a few models to help you decide which one might be the best fit for your home.
The Blueair Blue Signature Air Purifier covers up to 63 square meters, making it suitable for larger rooms. In comparison, the Blueair Blue Max 3350i has a bigger reach, covering up to 86 square meters. This makes it great for more spacious areas. On the other hand, the Shark NeverChange5 Air Purifier HP150UK can handle rooms up to 60 square meters, which is good for medium-sized spaces.
In summary, if you have a larger area to purify, the Blueair Blue Max 3350i would be the best choice. For smaller rooms, the other options are still effective but might not be as powerful.
Noise Levels & Sleep Mode
When choosing an air purifier, noise levels are important, especially if you plan to use it while sleeping. The Blueair Blue Signature Air Purifier is known for being quiet, with a sound level of only 40.8 dB on low, which is about the same noise level as a whisper. This makes it a great choice for nighttime use.

Filter Replacement & Operating Costs
When choosing an air purifier, it’s essential to consider how often you’ll need to replace the filters and the overall running costs. The Blueair Blue Signature Air Purifier is known for its easy-to-remove filters, which last between 9 and 12 months.

While it cleans air quickly, it’s not the most portable design. Additionally, the Shark NeverChange5 Air Purifier is smaller but can be noisy, especially at higher settings, which may lead to increased running costs if used frequently at max power.
