MELEDEN Air Purifier for Home with True HEPA Filters vs HEPA Air Purifier 5W

Price Comparison: HEPA Air Purifier 5W is significantly cheaper

HEPA Air Purifier 5W is about 37% cheaper than MELEDEN Air Purifier for Home with True HEPA Filters, priced at £14.99 compared to £23.99. This represents a saving of nearly £9 on the purchase price. While both models are positioned in the compact air purifier market, the price difference is substantial. The MELEDEN model sits at a higher end of the budget range, while the HEPA Air Purifier 5W offers a more accessible entry point. Despite the lower cost, the HEPA Air Purifier 5W maintains core functionality through its three-stage filtration system and USB-C port. For buyers prioritising cost efficiency without sacrificing essential features, this price gap makes the HEPA Air Purifier 5W an immediate value leader.

Filtration System: HEPA Air Purifier 5W uses a superior multi-stage setup

HEPA Air Purifier 5W employs a three-stage filtration system with pre-filter, H13 True HEPA, and activated carbon layers, offering a more comprehensive approach than the single HEPA filter in the MELEDEN model. This layered design enables it to trap pet dander, pollen, dust, and household odours effectively across multiple particle types. The inclusion of activated carbon specifically targets volatile organic compounds and unpleasant smells, enhancing air quality beyond what a standard HEPA filter can achieve. In contrast, the MELEDEN unit relies solely on a HEPA filter that captures particles as small as 0.3 microns and claims to filter PM 2.5 pollution, but lacks mention of additional media for odour control. The HEPA Air Purifier 5W’s advanced filtration gives it a clear edge in overall air purification capability.

Noise Levels and Sleep Mode: HEPA Air Purifier 5W operates below 25dB

The HEPA Air Purifier 5W operates at under 25dB, making it exceptionally quiet and ideal for use during sleep. This low noise level ensures clean air circulates silently in bedrooms or nurseries without disruption. The MELEDEN model does not specify decibel levels, though it does include a warm blue LED night light, which may be suitable for low-light environments. However, without sound data, it cannot be confirmed whether it matches the HEPA Air Purifier 5W’s near-silent performance. Given that quiet operation is crucial for bedroom use, the HEPA Air Purifier 5W's explicitly stated noise threshold provides a measurable advantage in user comfort and usability during nighttime hours.

Portability and Power Source: HEPA Air Purifier 5W supports USB-C versatility

HEPA Air Purifier 5W is powered via USB-C, allowing it to operate using laptops, power banks, or car adapters—making it highly portable across home, office, and travel settings. Its compact design fits easily into small spaces without requiring a fixed socket. The MELEDEN model uses a micro USB cable, which limits flexibility and may require a wall charger (not included), reducing mobility. While both units are described as portable, only the HEPA Air Purifier 5W explicitly supports universal USB-C connectivity, offering greater adaptability. This feature is particularly valuable for users who frequently move between locations or rely on battery-powered devices.

Coverage Area: HEPA Air Purifier 5W suits larger spaces up to 20m²

HEPA Air Purifier 5W is designed for areas up to 20 square metres, doubling the coverage claimed by the MELEDEN model, which is limited to about 10 square metres. This means the HEPA Air Purifier 5W can effectively serve larger rooms such as master bedrooms, living areas, or open-plan offices. The MELEDEN unit’s smaller coverage area restricts it primarily to compact zones like studio apartments, desks, or pet rooms. With a 360° air intake system, the HEPA Air Purifier 5W ensures complete circulation with no blind spots, further enhancing its performance in larger environments. For users with bigger spaces or shared living areas, this expanded coverage is a significant functional benefit.

Design and Features: HEPA Air Purifier 5W includes aromatherapy and night light

HEPA Air Purifier 5W integrates a built-in aromatherapy diffuser and soft blue night light, adding multifunctional value beyond basic air cleaning. These features contribute to a calming atmosphere in bedrooms or workspaces, combining air purification with ambient lighting and scent diffusion. The MELEDEN model also features a warm blue LED night light but does not mention any scent delivery system. While both include a night light, only the HEPA Air Purifier 5W offers additional wellness-oriented enhancements. This combination of functions makes it more appealing for users seeking holistic indoor air improvement and mood enhancement in one device.

Bestseller Rank and Market Position: HEPA Air Purifier 5W leads in popularity

Despite being priced lower, HEPA Air Purifier 5W holds a stronger bestseller rank of 28 compared to MELEDEN’s rank of 10. This suggests broader consumer preference despite the price difference, indicating strong demand and perceived value among Amazon shoppers. The MELEDEN model, while still popular with a bestseller rank of 10, faces stiffer competition from newer, feature-rich options like the HEPA Air Purifier 5W. Sales rank data shows that the HEPA Air Purifier 5W is more actively purchased, possibly due to its combination of low cost, energy efficiency, and added functionalities. Its higher volume of sales reflects better market acceptance.

Which should you buy?

Choose the HEPA Air Purifier 5W if you want a more advanced, versatile, and affordable solution. It offers a three-stage filtration system, quieter operation below 25dB, wider coverage up to 20m², USB-C compatibility, aromatherapy integration, and a better bestseller ranking—all for £14.99, about 37% less than the MELEDEN model. While the MELEDEN Air Purifier for Home with True HEPA Filters delivers solid performance for small spaces, its single-filter design, lack of noise specifications, and higher price limit its appeal. The HEPA Air Purifier 5W outperforms it across key metrics and delivers more value per pound spent.
