Scentia Max Scent Diffuser vs LULACHE Waterless HVAC Scent Diffuser

The Scentia Max is the better-built, more polished diffuser for a home, with a 120 ml bottle, a 2,200 mAh battery that runs up to 200 hours on Eco, and five intensity levels plus work/rest cycles. The LULACHE targets much larger spaces and holds a 500 ml bottle, so it suits a hotel lobby, office or open-plan floor better than a bedroom. Owners of the Scentia praise the app and silent operation; the LULACHE's sparse spec sheet and short track record make it the riskier pick for a small room.

• Choose the Scentia Max if you want a quiet, cordless diffuser for a home room up to about 1,500 sq ft with app scheduling and a battery that lasts days.
• Choose the LULACHE if you need to scent a very large space like a lobby, office or open floor plan and want a big 500 ml reservoir with Wi-Fi control.
