Don’t let stale, stagnant air disrupt your household. The reasonably priced Coway Airmega 150 is an ideal HEPA air purifier for small spaces (up to 214 square feet). It has a minimalist design and a reliable air filtration setup. The last-mentioned bit includes a HEPA and a deodorization filter, as well as a washable pre-filter for larger airborne particles. The Airmega 150 has a compact footprint and intuitive controls, as well as a light indicator that changes color depending on the room’s air quality.
