Twelve questions we hear most often about the SR100.
What room size does the SR100 cover?
The SR100 is designed for rooms 129–161 sq ft (5–10 m²) — ideal for bedrooms, nurseries, home offices, and small living spaces.
How loud is the SR100?
Ultra-quiet 43 dB on sleep mode — about the level of a quiet library. You’ll barely notice it running overnight.
What does the 3-stage filtration include?
A pre-filter for dust and hair, a True HEPA H13 layer that traps 99.97% of particles down to 0.3 microns, and an activated carbon stage that absorbs odors and VOCs.
How often do I need to replace the filter?
Every 6–8 months under typical use. The SR100’s filter indicator tells you exactly when it’s time.
What is the Particle Count Meter display actually measuring?
A laser particle sensor reads the concentration of fine particulate matter smaller than 2.5 microns and reports it in micrograms per cubic meter. The display updates every few seconds.
How much electricity does it use?
Just 10W on standard operation — about the same as an LED bulb. You can run it 24/7 without worrying about your bill.
What are the dimensions and weight?
7.5″ × 7.5″ × 9.1″ (190 × 190 × 231 mm) and 1.2 kg. Small enough for a nightstand or desk corner.
What fan speeds does it offer?
Four speeds — Lo, Med, Hi, and Turbo — plus an Auto mode that adjusts the fan based on the Particle Count Meter reading in your room.
Is it safe around children and pets?
Yes. The built-in child lock prevents accidental setting changes, and the unit is fully enclosed with no exposed moving parts.
What color options are available?
The SR100 launches in a single White finish — designed to blend quietly into any room.
What's included in the box?
The SR100 unit (White), one pre-installed 3-stage filter, the DC 5V/2A power adapter, a quick-start guide, and the 1-year manufacturer warranty card.
What's your shipping and return policy?
Free U.S. shipping on every order, typically 3–5 business days. Try the SR100 risk-free for 30 days — return it in original packaging for a full refund. Backed by a 1-year manufacturer warranty.
