10 Best Air Purifiers For Mold Spores Washable Filter 2025 in the United States

The PuroAir HEPA Air Purifier stands out for those needing a robust solution for large spaces, covering up to 1,115 square feet. Its three-layer filtration system, which includes a pre-filter, HEPA filter, and activated carbon layer, is highly effective—claiming to capture up to 99.9% of various pollutants like dust, smoke, and allergens, making it an excellent choice for allergy sufferers and those sensitive to air quality. The quiet operation is a significant advantage, particularly for bedrooms, thanks to its built-in sleep mode, allowing it to run 24/7 without disrupting your peace.

While the large coverage area is beneficial, it may be overkill for smaller rooms, and some users might find it bulky. The maintenance aspect is manageable, but as with any HEPA filter, you will need to keep an eye on when to replace filters to maintain optimal performance. Additionally, while it’s backed by several certifications, some customers might have concerns about the air purifier's reliance on a smart particle sensor, preferring manual controls instead.

The two-year warranty adds a layer of confidence in the purchase, but its performance may vary based on the specific conditions and pollutants in your home. The PuroAir HEPA Air Purifier is a strong contender for anyone looking to improve indoor air quality, especially in larger rooms prone to mold and other allergens.

The LEVOIT Vital 200S-P air purifier is designed to tackle allergens, making it a good choice for people who suffer from allergies. It features a washable pre-filter, which helps prolong the life of the main HEPA filter that captures 99.97% of particles, including mold spores. This is a beneficial feature as it can save on replacement costs and ensure continuous high performance.

The purifier covers a large area, up to 1800 square feet, making it suitable for big rooms and even some whole-home scenarios. The Clean Air Delivery Rate (CADR) of 242 CFM means it can efficiently clean the air quickly, though it's worth noting that this performance relies on using Levoit's original filters. Noise levels are managed with a sleep mode that automatically adjusts fan speed for quieter operation, ideal for bedrooms or living areas where noise might be a concern. Additional smart features include WiFi connectivity, allowing control through the VeSync app to set schedules, adjust settings, and monitor filter life. This can be particularly useful for those with varied schedules or who want seamless integration with home automation systems.

However, the reliance on proprietary filters might be a downside for some, as off-brand filters are discouraged. The light detection feature is convenient, adjusting the display brightness based on room light, which can make the purifier less intrusive in dim environments. Potential users should be aware of the ongoing filter maintenance required to keep it performing optimally.

The Coway Airmega AP-1512HH is a versatile air purifier, particularly suitable for medium-sized rooms up to 361 square feet. It excels with its 4-stage filtration system, including a True HEPA filter, which effectively captures 99.97% of airborne particles as small as 0.3 microns—ideal for those concerned about mold spores and allergens. Its Clean Air Delivery Rate (CADR) is decent, with figures of 246 for dust, 240 for pollen, and 233 for smoke, making it efficient in maintaining clean air in its coverage area.

One of its standout features is the real-time air quality monitoring system, with a LED display that changes color based on air purity. This function, combined with an auto mode that adjusts fan speeds according to detected air quality, makes it user-friendly. The Eco Mode is an energy-saving feature, stopping the fan automatically when the air remains clean for 30 minutes.

The noise levels range between 24.4 dB to 53.8 dB, which should be quiet enough for most users, especially at the lower fan speeds. Its maintenance is straightforward, with a filter replacement indicator that notifies when it's time to wash or replace the filters. However, users should note that while the pre-filter is washable, the HEPA filter will eventually need replacing, which incurs additional cost.

While the product has a strong reputation, having won an award in 2018, it lacks some modern features like Wi-Fi connectivity that some might expect. Also, despite its coverage claim, it seems better suited for slightly smaller spaces than the maximum suggested room size. Its combination of features, awards, and ease of use make it a solid choice for those in search of an effective air purifier without too many bells and whistles.
