DIY Compact Air Purifier with Formaldehyde Filter

A compact air purifier designed for personal spaces like bedrooms, offices, and small living areas. This unit targets common indoor air irritants including pet hair, smoke, dust, and fine particulates (PM2.5), making it useful for households with pets or smokers seeking fresher air. The filtration system works to capture airborne particles that settle on surfaces and aggravate allergies or respiratory comfort. Formaldehyde removal is included in the filtration process—relevant for newer furniture or construction materials that off-gas. The DIY setup means you can position it where you need it most without professional installation. Ideal for renters, small offices, or anyone looking to supplement whole-home filtration in a single room. Works best in enclosed spaces under 200 square feet where air circulation is limited.
