Shark NeverChange5 Air Purifier HP072UK (Dove, 23 Sqm Coverage)

How long does the HEPA filter actually last?

The NeverChange5 HEPA filter lasts up to 5 years when used 12 hours daily on maximum fan speed in a 12 square metre room. This duration is based on GB/T18801-2022 testing standards measuring 50% CADR decline. Your actual filter life may vary depending on air quality, room size and usage patterns. The unit will indicate when filter replacement is needed.

What room size does this air purifier cover effectively?

This model covers up to 23 square metres with one complete air change per hour. For smaller spaces of 4 square metres, it provides 4.8 air changes per hour for more intensive purification. The coverage assumes standard ceiling heights of 2.4-3 metres. Larger rooms may still benefit but with reduced air change frequency.

Can I use the purifier without the anti-odour cartridge?

Yes, the air purifier functions perfectly without the anti-odour cartridge installed. The HEPA and DebrisDefence filters provide complete particle filtration independently. Some users prefer operating without the cartridge to avoid any added fragrance. Simply remove or don't install the cartridge if you want odourless air purification only.

How noisy is this air purifier during operation?

On lower fan speeds, the unit operates almost silently, suitable for bedrooms and quiet environments. Auto mode typically runs quietly once good air quality is achieved, only increasing speed when needed. Even at maximum speed, noise levels remain comfortable for watching television or conversation. The night mode dims lights whilst maintaining quiet operation.

Does this air purifier connect to smartphone apps?

No, this model doesn't offer smartphone app connectivity or remote control functionality. All controls are accessed through the touch-sensitive panel on top of the unit. You need direct line-of-sight to operate the controls. The Clean Sense IQ auto mode reduces the need for manual adjustments by automatically responding to air quality changes.

What maintenance does this air purifier require?

Regular maintenance involves cleaning the washable DebrisDefence filter by brushing or vacuuming accumulated debris. This should be done monthly or when visibly dirty. The HEPA filter requires no cleaning and lasts up to 5 years. The anti-odour cartridge may need occasional replacement, though no specific timeframe is provided by the manufacturer.

How effective is this purifier against pet allergens?

The 4-layer HEPA filtration system captures 99.97% of pet allergens including dander, hair and microscopic particles. The 0.1-0.2 micron filtration efficiency targets the smallest allergen particles that trigger reactions. Many users report reduced allergy symptoms and less visible pet hair in the air. The anti-odour technology also helps neutralise pet-related smells.

What's included in the box with this air purifier?

The package includes the main Shark NeverChange5 air purifier unit, one washable DebrisDefence filter, one NeverChange5 HEPA filter and one anti-odour technology cartridge. No additional filters or accessories are needed for initial setup. The unit comes ready to use straight from the box with all necessary components pre-installed or included separately.
