Improving indoor air quality is a key part of maintaining a healthy home environment, especially when dealing with mould and allergens. Air purifiers designed to tackle these issues work by filtering out airborne spores, dust, and allergens that can aggravate respiratory problems or contribute to damp-related concerns. In the UK, where damp and mould are common in many homes, choosing the right air purifier can make a significant difference.
Air purifiers that specifically target mould and allergens often combine HEPA filters with activated carbon or anti-microbial technologies to trap and neutralise contaminants effectively. Their design and efficiency vary widely, depending on room size, filter lifespan, and noise level. Because these factors directly affect performance and convenience, they are crucial to consider during purchase.
When selecting the best air purifier for mould and allergies, pay close attention to filter type and maintenance requirements, coverage area, and whether the unit includes features that combat mould spores directly. These elements determine how well the purifier fits your home’s conditions and your cleaning routine. We tested several models available in the UK to identify the best air purifiers for mould and allergies in 2025.

We’ve found the AONAT purifier easy to use and very discreet in operation. The low noise level means it doesn’t disturb sleep, making it one of the quieter models we’ve tested in its class.
The 360° airflow design helps circulate clean air efficiently, and the combination of pre-filter, HEPA, and activated carbon really handles common allergens and smells well. Adding scents through the aroma slot adds a subtle freshness, which is a nice bonus for those wanting more from their purifier.
Its compact size and USB power make it very flexible for different environments—ideal if you’re short on space or want a portable solution. However, it’s best suited for smaller rooms or desks rather than large living areas.

- Effective 360-degree intake cleans air evenly in small to medium rooms
Cons
- Filter replacement reminder can be easy to overlook
- Slightly limited fan speed options (only two)
- Not suitable for very large rooms due to coverage area
We found the Operan MR2566 to maintain a fresh atmosphere with minimal noise disruption. The sleep mode truly dims the unit’s lights and lowers sound to a barely noticeable 22dB, which helps improve rest without disturbance.
This purifier handled pet dander and typical household allergens well, noticeably reducing smells and particles in our tests. The ability to adjust fan speed means you can balance quietness with stronger air flow when needed.
Adding essential oils was a nice bonus, filling the room with a subtle scent that blends with clean air. Portability also stood out; it was easy to move around and set up quickly in different spaces.
This is a solid model for bedrooms or modest living areas if you want a mix of allergy relief and ambient scent control without breaking the bank.
PureMate HEPA Air Purifier
We found the PureMate HEPA Air Purifier to be an effective choice for reducing mould spores and allergy triggers in medium-sized UK homes.
Pros
- Highly efficient H13 HEPA filter captures nearly all airborne allergens
- Smart auto mode adjusts fan speed based on real-time air quality
- Very quiet operation, suitable for bedrooms and nurseries
Cons
- Slightly bulky for small rooms or tight spaces
- Touch controls can be sensitive, requiring careful handling
- Activated carbon layer may need frequent replacement in high odour environments
Using the PureMate purifier, we noticed a clear reduction in dust and pet dander after just a few days. The filtration feels powerful without being noisy, which means it can run overnight without disrupting sleep.
Its auto mode is particularly handy; the air quality sensor adjusts the fan speed as needed, so we didn’t have to keep fiddling with settings. This responsiveness makes it practical in homes where pollution levels vary during the day.
The unit is large, so it requires some floor space, but its clean, white design fits in nicely with modern home interiors. While the touch panel is intuitive, the sensitivity means you have to be gentle, especially if you have pets or children around.
Overall, if you want dependable allergen and mould removal with smart features and low noise, the PureMate air purifier is worth considering for UK homes up to 36m².
Levoit Core Mini
This compact air purifier efficiently clears mould spores and allergens, making it a solid option for smaller UK homes.
Pros
- Very low energy consumption keeps running costs minimal
- Three-stage HEPA filter effectively captures dust, pollen, and pet dander
- Aroma pad allows adding essential oils for a fresh, personalised scent
Cons
- Limited to rooms around 34 square metres, not suitable for large spaces
- Filter replacements needed every 4-6 months, adding ongoing cost
- Smaller size means airflow can feel less powerful in bigger rooms
We found the Levoit Core Mini easy to set up and intuitive to operate with only two control buttons. It remains quietly in the background, which is ideal for bedrooms or offices where noise can be a nuisance.
The HEPA filter noticeably reduced airborne particles quickly, and we appreciated that it never produced ozone or harmful by-products. Running it continuously is affordable given the very low wattage and electricity usage.
Adding essential oils via the aroma zone was a nice, subtle touch. However, while its coverage is good for smaller rooms, larger spaces would require multiple units or a bigger purifier. Overall, this unit delivers clean air with economical energy use.
PureMate Air Purifier
A solid choice for anyone needing reliable mould and allergy control in small to medium indoor spaces.
Pros
- Effectively captures mould spores and common allergens
- Simple controls with useful sleep mode and adjustable night light

In rooms treated for mould, it noticeably reduced airborne spores and dust after a few days. The unit’s compact size means it fits well in bedrooms or offices without being intrusive.
Filter replacement alerts are a neat feature, ensuring we never missed changing the 3-in-1 filter. While the running costs from filter changes are something to consider, the overall performance justifies the expense for cleaner air.
Buying Guide
Choosing the best air purifier for mould and allergies requires careful consideration of several key features. We should prioritise filtration efficiency, especially HEPA filters that capture tiny particles like mould spores and allergens.
Next, room size compatibility is important. We must match the purifier’s capacity to the size of the room for effective air cleaning. Look for units that specify the square metre coverage to avoid underperformance.
Another critical factor is the air exchange rate or CADR (Clean Air Delivery Rate). This rate tells us how quickly the purifier can clean the air in a given space. Higher CADR values are better for faster purification.
We also recommend checking the noise level, especially if the purifier will run in bedrooms or living areas. Quiet operation is preferable to maintain comfort throughout the day and night.
Energy efficiency is worth considering for cost savings and environmental impact. Units with energy-saving modes or low power consumption can help us reduce running costs.
Maintenance is part of the ownership experience. We should consider how often filters need replacing and the availability and cost of these filters. Easy-to-change filters add convenience.

| Room Size Coverage | Appropriate square metres | Ensures purifier can handle the space |
| Air Exchange Rate | High CADR values | Faster air cleaning |
| Noise Level | Low decibel output | Comfortable environment |
| Energy Efficiency | Energy-saving modes, low consumption | Saves money and energy |
| Filter Maintenance | Frequency and cost of replacements | Convenience and ongoing costs |
