Bring cleaner, fresher air into your home with the SV-6113 air purifier by Sollievo. A 6-stage filtration system ushers air through a washable pre-filter to capture larger particles before moving it through charcoal, activated carbon, true HEPA, anion continuous negative ion generation, and antibacterial peptide filters to remove allergens, smoke, odors, germs, and other minute yet harmful air pollutants. Allergy and asthma sufferers will especially benefit from the True HEPA filter, which removes 99.7% of airborne particles as small as 0.3 microns.
