# How to Choose a Scent Diffuser by Space Size

Published: Original publication date not recorded · Updated: 2026-10-31

Use volume, not floor area. SDL312 and SDL313 list 200–500 m³; SDL611 lists 500 m³; SDL614 lists 1500 m³; SDL613 lists 2500 m³; SDL616 and SDL821 list 4500 m³; SDL820 lists 10000 m³.

## Buyer problem

Stated coverage is a starting point for selection. Layout, ventilation, ceiling height and operating schedule influence suitability and should be reviewed with the team.

CompactSDL312, SDL313 (200–500 m³) and SDL611 (500 m³).

MediumSDL614 (1500 m³) and SDL613 (2500 m³).

LargeSDL616 and SDL821 (4500 m³).

Large-scale projectsSDL820 (10000 m³, 1000 ml × 2).

Decision criteria

## What to confirm before ordering.

1. 01
Calculate room volume in m³ from length, width and height.

2. 02
Consider separate zones rather than one combined volume.

3. 03
Check placement, power supply and refill access.

4. 04
For HVAC projects, obtain installation compatibility confirmation; do not assume a direct duct connection.

FAQ

## Quick answers.

Can I use floor area to select a model?

Coverage is stated in cubic meters, so convert your floor area using ceiling height before comparing.

Is the stated coverage guaranteed for every site?

No. It is the stated specification; site conditions should be reviewed for each project.
