10 Best Air Purifier For Mold Spores Mildew 2026 in the United States

The LEVOIT Core P350-P Air Purifier is a solid choice for pet owners dealing with mold spores, mildew, and other allergens. One of its standout features is the HEPA filter, which is crucial for capturing mold spores along with pet dander, dust, and pollen. It also includes an efficient activated carbon filter specifically designed to neutralize pet odors, smoke, and other household smells effectively.

With a CADR (Clean Air Delivery Rate) capable of purifying a 219 ft² room in just 12 minutes, it's suitable for medium to large rooms, but may require more units for very large spaces or open floor plans. The noise level is impressively low at 24dB in sleep mode, ensuring a peaceful environment at night. The air purifier includes a pre-filter that traps larger particles, which can reduce the frequency of cleaning your home. While the unit is CARB certified, indicating it meets strict safety standards, a potential downside is the need for regular filter replacements, which can incur additional costs. Also, the coverage area might be insufficient for very large rooms.

Additional features like the pet lock make it family-friendly, preventing accidental changes to settings by pets or children. The product is easy to use and maintain, but always opt for the official Levoit replacement filters to ensure optimal performance. This air purifier is ideal for pet owners looking for a device that combats both pet-related allergens and household odors while maintaining a safe and quiet home environment.

The LEVOIT LV-H132 air purifier is a solid choice for improving indoor air quality in small to medium rooms up to about 263 square feet, which fits well for bedrooms, offices, or nurseries where mold spores and mildew might be a concern. It uses a true HEPA filter combined with activated carbon and a preliminary filter, effectively capturing tiny particles like dust, pollen, and mold spores as small as 0.3 microns. This 3-layer filtration is key for tackling mold spores and musty odors.

An important advantage is the AHAM verification that confirms its air cleaning performance meets trusted standards, giving you confidence in its effectiveness. It also runs quietly at 28 decibels, making it unobtrusive during sleep or work. The option for a night light with adjustable brightness is a nice extra for bedrooms. Its energy consumption is low at 11 watts, so it won’t drive up electricity costs.

The purifier is fairly compact and lightweight, so it’s easy to place or move around. Filter replacement is straightforward with official Levoit filters recommended to maintain optimal performance and avoid damage. This model offers dependable HEPA filtration and quiet operation tailored for smaller spaces where mold spores and allergens are a problem. It’s user-friendly and certified for safety and efficiency, though those needing faster air cleaning or larger area coverage might consider other models.

The PuroAir HEPA Air Purifier is designed to effectively improve air quality in large spaces, covering up to 2,145 square feet. One of its greatest strengths is the HEPA filter, which is capable of capturing up to 99% of harmful pollutants, including mold spores, dust, and smoke. This makes it particularly beneficial for individuals with allergies or sensitivities to airborne particles.

The air purifier features a smart particle sensor that automatically adjusts the airflow based on the air quality. This means that you can set it up and let it run continuously without much hassle. Additional features like a timer, fan speed options, and sleep mode enhance its usability, making it suitable for bedrooms and living areas alike. Plus, with a noise level of just 36 dB, it operates quietly, ensuring minimal disruption during use.

There are a few things to consider. While the coverage area is impressive, the purifier’s size and weight (16 pounds) might be cumbersome for some users, especially if you need to move it between rooms. The filter replacement and maintenance could also be a concern for some, as regular upkeep is necessary to maintain optimal performance. This air purifier is a great choice for those looking to combat mold and improve air quality in larger spaces, but it may require a little extra effort in terms of maintenance to keep it running effectively.
