Had one in my purse during a wedding and ended up passing it around like perfume. Everyone loved it. I’ve since ordered refills and one for my partner too.
Store owner replied: We love knowing the product added such a unique touch to your special moment. Thanks for sharing your wonderful experience!
I’m in sales and talk all day. This gives me confidence before every pitch or handshake. One spray and I know I’m set, no second-guessing.
Store owner replied: Thanks for your wonderful feedback, and we look forward to continuing to support your success!
I honestly didn’t expect the fresh feeling to last. But this thing holds up, even through dinner or a few drinks. Saves me from that “ugh I should’ve brushed again” vibe.
Store owner replied: Thanks for sharing your experience, and we look forward to seeing you for more refreshing moments!
Bought it thinking it’d be a cool gadget, but didn’t expect to actually love it. I spray it after a meal or coffee and it’s just reliable. Feels like a product made for grown-ups.
Store owner replied: Your feedback truly inspires our commitment to quality and innovation. Thanks for being a valued part of the HolyH2O community, and we look forward to serving you again soon!
It doesn’t feel like a product I have to use, it’s one I want to use. Like how skincare becomes a ritual. One spray and I feel instantly better.
Store owner replied: Your words truly capture the essence of what we strive for. Thank you for sharing your experience, and we look forward to being a part of your refreshing rituals!
After a long day of commuting and talking, I feel dry and cranky. This is like a reset button for my mouth. Just a little mist and I feel cleaner, calmer, and a bit more “me”.
Store owner replied: Your experience perfectly captures the essence of what HolyH2O™ stands for. Thanks again for sharing such a thoughtful review!
The fine mist makes all the difference. It doesn’t feel like you’re attacking your mouth, just freshening it. Honestly kind of addictive in the best way.

Can’t use gum with Invisalign and mints melt in my pocket. This has been a game-changer. Quick, hygienic, and the gf actually notices when I use it, in a good way.
Store owner replied: We're thrilled to hear that Cool+ has been such a game-changer for you. Thanks for your wonderful review!
I chewed gum like it was a nervous habit. This spray gave me a cleaner, more conscious alternative. Feels good in the hand, fresh in the mouth, and I don’t feel gross after.
Post-gym, I used to use mouthwash from my glovebox like a savage. Now I spray this before I drive home and feel way more human. It’s part of my cool-down now.
I accidentally left mine at home one day and realised how much I rely on it. There’s something about knowing you’re covered, no matter what. It’s like wearing deodorant, you just feel better.
I get nauseous with artificial mint stuff, so I’ve avoided breath sprays for years. Cool+ was surprisingly smooth. It doesn’t burn, just refreshes in a way that feels natural.
I hate chewing gum in meetings, it feels unprofessional. This spray is clean, quick, and way more mature. I feel more confident knowing I’m fresh, not fruity or artificial.
First time I used it was at a music festival - I felt gross, sweaty, and dusty. One spray and I felt like a new person. Legit reset my mood. Now I don’t go to events without it.
Used to feel super anxious after meals, always second guessing my breath. This spray gives me peace of mind instantly. It’s become as essential as my wallet or phone. Thanks HolyH2O!
It’s weird how something so small can feel so premium. I spray it before I do my makeup or head to the gym. It makes me feel polished, even if I’ve just rolled out of bed.
Took this on a surf trip up north and everyone ended up borrowing it. It’s perfect when you’re out all day and just want to feel fresh before dinner or drinks. Ended up ordering 3 more when I got home.
I talk all day on the job and don’t have time to sneak off for mouthwash. This fits in my apron and gives me a proper refresh between shifts. Feels more adult than gum and doesn’t feel like I’m masking bad breath - it fixes it.
Tried a breath spray once in high school and it tasted like petrol. This is a completely different experience. Soft, cooling, and actually enjoyable to use - like a breath spa.
After flying my mouth always feels dry and stale. This spray saved me on a long-haul from Sydney to Perth. It’s hydrating, subtle, and made me feel human again mid-flight.
I saw this on Instagram and thought it looked cool so gave it a shot, had no idea it’d become my new daily habit. One spray, instant freshness. No sting, no sticky aftertaste. It’s part of my routine now, like checking my phone.
It lives in my tote bag now, next to my lip balm and keys. I used to carry gum that melted or made my bag smell weird. This feels luxe, reliable, and somehow still low-key.
Went out for tacos on a first date and used this spray just before leaning in for a hug. She literally said “You smell so clean” - not even joking. Safe to say this thing’s coming with me everywhere now.
Lunch at my desk used to mean stressing about garlic breath before meetings. Now I spray this and it’s like a reset. No sugary gum, no fake mint. I feel professional, polished, and still myself.
I’ve got back-to-back Zooms most days, and no time to brush or chew gum like a teenager. Cool+ Spray is my secret weapon. Quick, clean, and it actually makes me feel sharp. I love this :)
After coffee I always felt like my breath betrayed me, even if no one said anything. This spray changed that. One mist and I feel genuinely fresh, not masked. I even caught myself smiling more during conversations, it gave me my confidence back.

Very handy, flavour acceptable, great for travelling
Nifty little gadget,sleek in size and the flavours are so nice I have confidence knowing my breath is fresh in a quick spray after coffee or a garlicky meal
Great test. Fast delivery
Took a chance on this and glad I did. Gets rid of coffee breath without feeling fake. Looks sleek and works even better.
Feels like something out of a skincare routine — but for your mouth. Perfect for post-gym or travel days. I’ve already told friends about it.
Didn’t expect to love this so much. Fits in any pocket or bag I’ve got. Best breath product I’ve used so far.
Honestly impressed. Always comes in handy after a meal. Would definitely recommend.
Confidence booster, no joke. I use it before meetings or heading out. Buying another one just to keep in the car.
I keep this on me 24/7 now. Works well right after brushing too. Tastes fresh without being overpowering.
Honestly impressed. Gets rid of coffee breath without feeling fake. Tastes fresh without being overpowering.
Nice design and feel. Great to have on me when I need it. Might try a different flavour next time.
Such a clean, stylish little product. Super useful during workdays and commutes. Subtle and super effective.
Click in your flavour pod, hold the device about 3 cm from your mouth, and mist for 3 seconds. That’s it. Use it whenever you need a refresh - before meetings, after meals, or on the go.
Get up to 6 hours depending on your lifestyle and diet. Many customers find they use it just 2–3 times a day to stay feeling fresh.
Most gums and mints mask odour with sugar or artificial flavouring. Cool+ Spray uses an ultra-fine mist and a probiotic blend to target the root cause of bad breath, helping support your oral microbiome, not just hide it.
Plus chewing-gums rank 2nd among the most polluting wastes on the planet. Most of them are composed of synthetic and non-biodegradable plastics which causes 250,000 tons of waste each year, 80% of which is dispersed into the environment and the sea.
