05 The numbers that actually differ
Six fields decide the purchase. Everything else is the same across the range.
| Model | Width | Max CFM | Static pressure | Noise | Venting | Price |
|---|---|---|---|---|---|---|
| R-Max3 30" / 36" | 30 / 36" | 1,400 CFM | 1,200 Pa | 38 dB | Ducted / ductless | $1,349 |
| 88H3S | 36" | 1,500 CFM | 1,000 Pa | 49 dB | Ducted | $2,399 |
| 86H1S | 30" | 1,300 CFM | 1,000 Pa | — | Ducted / ductless | $1,399 |
| A679S | 36" | 1,300 CFM | 1,000 Pa | 34 dB | Ducted | $1,499 |
| A831 | 30" | 1,100 CFM | 800 Pa | 42 dB | Ducted / ductless | $1,199 |
| U3 | 30" | 1,000 CFM | 800 Pa | — | Ducted / ductless | $599 |
Noise is the manufacturer's low-speed rating.
06 Not sure? Get your number
Five taps. Both sizing rules applied, duct loss added.
A shopping target, not an engineering certification.
07 Will it fit your kitchen?
Three things to check before you order.
1 · Mounting type
Keeps your cabinets
Fits an existing run. Costs you depth inside the cabinet above.
Needs a free wall
Duct hidden in the chimney. Add an extension above an 8 ft ceiling.
Captures at the pan
Angled intake, clear headroom above the cooktop.
2 · Size
The hood must be at least as wide as the cooktop.
Red zones never reach the hood.
3" of capture margin on each side.
3 · Ducting
Ducted
Air leaves the building
- Smoke and steam
- Heat
- Humidity
- Gas combustion by-products
- Needs a route to an outside wall or roof
Ductless
Air is filtered and returned
- Grease
- Most odour
- No duct work
- Heat
- Humidity
- Carbon monoxide from gas
Convertible: U2, U3, A831, A832, 86H1S, both R-Max3 sizes.
Why static pressure matters
Resistance is not measured in feet of pipe.
A 450 Pa motor runs out of force here. A 1,000 Pa motor does not.

10 What owners actually say
The quiet power of this range hood is impressive, it clears smoke and odors in seconds, yet you barely notice it's on.
Jessica Miller · Boston, MA · A831
Even during holiday feasts with multiple dishes cooking, the R-Max3 maintains crystal-clear air throughout our open-concept kitchen.
Barbara Johnson · Atlanta, GA · R-Max3
Searing steaks used to fill my kitchen with smoke — now the A679 clears the air completely while keeping the flavor perfect.

11 Common questions
What CFM do I need for a 30-inch gas range?
Start at 900 CFM. Burner BTU divided by 100 gives 600 for a typical range, and ducting takes 30–40% of that away.
Do I need make-up air?
Above 400 CFM, most US jurisdictions require it. Confirm with your local building department before you order, not after.
Can a ductless hood remove smoke?
It removes grease and most odour, not heat, humidity or gas combustion by-products. Fine for induction; not for daily high-heat gas.
How high should it be mounted?
24–30 in above electric, 27–33 in above gas. The manual for your specific model always overrides the general rule.
What duct size?
6 in round minimum above 600 CFM, 8 in above 1,200 CFM. A 4 in duct left from an old microwave will throttle any modern hood.
How often do filters need cleaning?
Mesh and baffle filters go in the dishwasher every 2–4 weeks. Charcoal cartridges are replaced every 3–6 months and are not washable.
