Mask Co discount codes and coupon codes in November 2026

We update the codes on this page regularly, so you're not stuck with one that expired last week. The trick is knowing where a code earns its keep.

Percentage codes do the most on full price items and bigger orders, such as a multi pack of refills, because the saving grows with the cart. On a single marked down spray, the sale price alone is often the better deal, so add both options to your cart and keep whichever gives the lower total. Codes can also come with a minimum spend or exclusions, and a code that fails at checkout usually means your cart doesn't meet those conditions rather than the code being dead.

Mask Co runs a Rewards program, linked from the main menu on their site, where you collect points as you shop and swap them for rewards on later orders. Join before your next order so it counts towards your balance.

Points suit people who top up the same room spray or diffuser every month or two, since those orders build a balance with no extra spend. A single spray once a year won't earn much. Based on our research, holding your points for a larger refill order gets you a more noticeable discount than cashing in a small balance on one item.

The Happiness Guarantee refunds up to 3 scents per order that aren't right for you, and you don't need to send anything back. There are no exchanges.

• Email hello@maskco.com within 30 days of receiving your order.

• It covers fragrances such as air fresheners, toilet sprays, fragrance oils, reed diffuser refills, body mists and perfume oils, but not candles, incense, electrical items, or reed bottles and sticks.

• A single item from a bundle is refunded at an adjusted value, not the bundle price.

• Each customer can use the guarantee 3 times.

That makes a new scent close to risk free, so it's a fair reason to try something unusual at full size. Save your 3 claims for scents you genuinely dislike.
