Honeywell room purifiers use True HEPA filtration to reduce indoor particles such as dust, pollen and pet dander. For odors and gases, choose models with activated carbon or gas-phase media and size the unit to your room.
Sharp combines True HEPA filtration, activated carbon, and its Plasmacluster ion technology. These purifiers remove common allergens and odors, but claims about sterilizing air or preventing illness depend on model- and study-specific evidence.
Mainstream reviews often highlight widely sold air purifiers, which can leave out high-performance or specialty units. Use True HEPA, CADR, certifications, and independent tests to compare models and find the best match for your needs.
Holmes makes consumer air purifiers that pair HEPA (or HEPA-style) filtration with activated carbon for particles and odors. Use CADR, ACH and confirmed filter type to match a model to your room and health needs.
Practical guidance on choosing a portable air purifier: pick a True HEPA unit sized for your room, consider activated carbon for odors, check CADR and filter costs, and weigh portable versus whole-house options.

Compare CADR, True HEPA, filter costs, noise, and safety to pick an air purifier that matches your room size and pollutant concerns.
Holmes offers compact, quiet air purifiers suited to single rooms. They provide moderate particulate removal but usually lack True HEPA certification, high CADR, and strong odor control - so they're not ideal for whole-house use or severe allergy and asthma needs.
