Editor's Pick: If you have pets at home or suffer from nasal sensitivity during pollen season, this purifier is quite practical. The HEPA filter captures particles as small as 0.1 microns, even finer than standard HEPA filters, and the brand claims you won't need to replace it for five years. The automatic mode adjusts fan speed based on air quality, so you don't have to worry about changing settings when sleeping. It covers up to 1,400 square feet (130 square meters), making it sufficient for living rooms or open-concept kitchens.
