​I had a frustrating experience buying a rhinitis device from a Facebook/Shopify ad (not realizing it wasn't a genuine NovaFlow). I ended up with a cheap, unbranded device that felt unsafe. ​I reached out to Cleriva for advice, and their support team was amazing. They explained the safety risks of using unverified devices and, to my surprise, offered to send me a genuine NovaFlow device to ensure I had a safe and effective experience. It’s rare to find a company that cares this much about consumer safety and brand reputation. I’m now a loyal customer!

I've been using the novaflow for less than a month and the constant dry nose accompanied by bleeding has completely resolved. I can breathe easy, don't sneeze constantly and my nightime snoring has hugely reduced. No longer any need to use prescribed steroid nasal spray. I contacted the company to check if it's safe to use the device without the protective sleeves (as I gave very small nostrils) and got a speedy response.

I’ve been using NovaFlow for over 2 weeks now and so far have been really impressed with the results. After using it on day 1 i could noticeably breathe more easily, but still felt the congestion pressure. But after a couple of days that congestion feeling went. The biggest differences i can notice are being able to breathe through both nostrils, at the same time! It’s quite a novelty, i’ve only ever been able to do that with nasal sprays previously. Also just breathing normally there doesn’t feel like any obstructions where previously i always felt like i wasn’t getting enough air in. I haven’t been waking up with a horribly dry mouth in the night either from mouth breathing. I would absolutely recommend this to anyone who struggles with sinus problems. I’ll take a glowing red face a few times a day for these results! Alex, 43.

I purchased the NovaFlow in late December after years of sinus issues, rinsing every day, and taking allergy medications. I did notice the first time I used it my nose felt less full and clogged. I’ve been using it once a day and have noticed my nose being less stuffy. I am also a cpap user who couldn’t sleep on my side due to my nose being continually clogged on one side. I can now sleep on my side again. I do want to note that the customer service was quick and responsive; my pup decided it looked like a chew toy. I contacted the rep and they immediately worked with me to help me out. Thank you!

I've been using my new NovaFlow red laser nasal therapy for just over a week for my non-allergic rhinitis, post-nasal drip, and sinus pressure in all my sinuses. I also have a perforated septum, so my sinus irrigation just flows straight through the hole & not into my sinuses. I'm starting to be able to tell a real difference. It's the dead cold of winter, but my nose isn't runny & having to blow my nose every 30 minutes as usual. No, just a few times a day really. It isn't uncomfortable to use, & each session (I'm using it twice a day) is about 10 minutes long. I got the kit with the UV sterilizer, extra nasal tips, & carrying case. The carrying case is way too large for my liking. The UV sterilizer does a good job I assume, as it has 2 UV LEDs & a viewing window. It's rather strange that the device charges with an ancient micro-USB charger, but the UV sterilizer uses USB-C. C'mon, get with the times! This is 2026! micro-USB is a thing of the past! That's really the only complaint that I have about the device & kit so far. Time will tell if I'm able to get off the 2 antihistamines & the Flonase I use twice a day, every day. Thanks for showing me something in a Facebook ad that I didn't know that I needed! I scrolled right past the ad several times, but I'm glad that you were persistent. I really think this is going to work after DECADES of doing the same old crap with antihistamines and steroids, KNOWING that they don't work with NON-allergic rhinitis, which is the diagnosis I received after 2 rounds of allergy testing about 6 years ago! I spent over 30 years taking meds that COULDN'T help!

Excellent customer care from Coney Angel Arcilla, Cleriva Support Manager- prompt and helpful. very impressed!

I was very skeptical about this, but after years and years of using decongestion spray over and over, several times a day, I decided to give this a try. It is working!! For me I noticed no difference until about 3 weeks of using it, but I did it daily 3 times a day anyway. After 3rd week I started noticing improvement. I am into my 4th week and I am now down to just using spray ONE TIME right before bed. So it does work, but it may take awhile. I am so hopeful that I can stop the sprays all together and finally get lasting relief. If it continues to work and show improvement, I will be ordering another one for backup.

Been using a Netty Pot for years. The Nova Flow is a game changer. I suffered from extreme allergies and sinus congestion. The NovaFlow has worked tremendously on my nasal congestion. Recommend.
