Not necessarily. While higher-priced units often offer stronger filtration, efficiency depends on matching the system to home size, maintenance, and filter type rather than price alone.
It varies by filter type and usage, but many filters require replacement every 3 to 6 months; high-efficiency HEPA filters might last longer depending on air conditions and usage.
Only systems with activated carbon or specialized filters can effectively reduce odors or some chemical pollutants; basic particulate filters mainly address dust and allergens.
It’s possible, but professional installation is recommended to ensure proper sealing, ductwork compatibility, and optimal performance.
Running it continuously helps maintain consistent air quality, but intermittent use might suffice depending on air conditions, occupancy, and ventilation — though continuous operation usually yields the best results.
