Frequently asked questions
How big a room does the Sharp FP-S42EU-L cover?
AHAM suggests it for a room up to 206 square feet. That rating assumes it runs on high and cleans the air about 4.8 times an hour. For faster cleaning — say for wildfire smoke or allergies — size it to a smaller room than the maximum.
What is the CADR of the Sharp FP-S42EU-L?
Its AHAM Clean Air Delivery Rate is 141 for dust, 133 for smoke and 152 for pollen, with a PM2.5 CADR of 137. CADR is cubic feet of clean air delivered per minute — higher clears a room faster.
Does the Sharp FP-S42EU-L use a real HEPA filter?
Its filter is listed as True HEPA (H13) + activated carbon. True HEPA captures 99.97% of particles down to 0.3 microns. The activated-carbon layer also helps with odors and gases.
How much power does the Sharp FP-S42EU-L use?
Power draw isn't published for this unit.
Where can I buy the Sharp FP-S42EU-L?
It's a retail unit, so the fastest way to find it is to search for the exact model on Amazon and compare current sellers and price. The replacement filters are the recurring cost — check those before you commit to a brand.
Sources. Clean Air Delivery Rate (dust / smoke / pollen), PM2.5 CADR, suggested room size, ENERGY STAR status and power draw come from the AHAM Verifide air-cleaner directory (the industry's independent CADR test). Average CADR, clean-air-per-watt and the percentile figures are computed by Verified HVAC Data from those published ratings. We publish no star ratings and take no payment for placement. "Not published" means AHAM's record doesn't disclose it — we never fill a spec with a guess.
