INFINITY vs Brilliant Scents: What $399 Buys You From Each

Brilliant Scents has been in HVAC scenting for years and knows the category well. If you're comparing them to our INFINITY, the honest answer is that both use the same underlying technology — cold-air nebulization, no heat, no water, connected to your supply duct.

The difference is what a given budget buys you. So let's do it that way, in dollars.

What $399 gets you from each

At the time of writing, Brilliant's LX1200 v2 is listed at $399.99, marked down from $999. It covers up to 1,200 sq ft, connects to HVAC or runs standalone, and has app control.

The INFINITY is $399 for the unit, or $449 with three 200ml oils included. It's rated for up to 16,000 sq ft and handles HVAC systems up to 10 tons.

Same money. One is sized for an apartment; the other is sized for a building.

Mila Marie INFINITY	16,000 sq ft	$399 — $449 with three oils

Read down the coverage column and the pattern is clear. To get past 5,000 sq ft with Brilliant, you're at $899.99 for the LX5000 v2, and their only unit rated near INFINITY's range is the flagship LX6000 — offered on a 24-month subscription that totals roughly $5,000.

An honest caveat about coverage numbers

Every square-footage rating in that table, ours included, is manufacturer-stated. There's no shared testing standard for scent coverage, and real performance depends on your ceiling height, floor plan, how often your blower runs, and the intensity you set.

What the numbers are good for is comparing intent — which unit a manufacturer built for a house versus a room. On that basis the gap here is not subtle. But treat any coverage figure as a starting point, not a guarantee, and size up if your ceilings are tall or your plan is broken up.

Where Brilliant Scents is the better choice

Three situations, and we'd rather tell you than have you find out after buying.

You want to scent a very small space. Their entry unit covers 150 sq ft at $64.94. We don't make anything that small — our smallest is the ECHO Mini at $89 for up to 700 sq ft, which is more machine than a powder room needs.

You want a very large fragrance library. Brilliant runs a deep catalogue across many themed collections. Our range is deliberately tighter — fewer scents, chosen carefully. If browsing dozens of options is part of the fun for you, that's a real point in their favour.

You want hardware extras. Their LX1200 v2 includes an oil-level sensor and a tip-over alarm. Useful features, and worth weighing if a standalone unit will be sitting somewhere a pet or child can reach it.

Where we think INFINITY wins

Coverage per dollar. Covered above. It's the whole argument.

Oil included in the bundle. A diffuser without oil produces nothing. INFINITY at $449 ships with three 200ml oils — $147 of fragrance for $50 more, so you're scenting on day one rather than placing a second order.

Buying outright rather than subscribing. Their largest system is sold as a monthly commitment. We'd rather you own the hardware and buy oil when you want it.
