Holmes sells compact and tower air purifiers combining HEPA or HEPA-type filters, activated carbon and optional ionizers. Prioritize True HEPA, check CADR and room coverage, and beware of ozone from ionizers.
An updated guide to Holmes replacement filters - wick, activated carbon and HEPA - how they work, when to replace them, and buying tips for compatibility and performance.
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.
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.
