About This

• COMPLETE REPLACEMENT - Our carbon pre-filters greatly reduce the amount of dust & particles getting into your main filter. Replacing your main HEPA filter is costly so with 4 pre-filters, you can save both time & money.
• NO MORE MEASURING AND CUTTING - Measuring and cutting filters are time-consuming and potentially inaccurate. Now you can replace your dirty old filter in a matter of minutes! These are specially cut and designed to fit HW HPA300 Air Purifier (this is the air purifier with 3 HEPA filters). Pre-Filter Dimensions: 14.2” x 17.2” x 0.2”.
• REMOVE ODOR, SMELL, AND SMOKE - Made from Premium Quality Activated Carbon to help keep your home smelling fresh and odor free. Ideal for households with pets, cooking, smokers & people suffering from asthma or allergies.
