In my experience NovaFlow works better than over the counter sprays or allergy pills. I’ve been using it for 6 months 2x a day and have had very good results here in our high altitude dry climate. It’s easy to use and the charge lasts a long time. No more OTC pill drowsiness and dryness caused by pills and sprays. Novaflow is a better alternative and it’s backed by super customer service. Try it, I think you’ll like it.
Real person here and i cannot praise this little item enough! For just short of 2 years I've been seeing an ENT Dr, about my sinuses and headaches, ive had cameras, drops (yes nasal drops) sprays, tablets the lot, and i seemed to get a little relief (around 20%) but then i came across an Advert for the Cleriva NovaFlow, i ummmed and ahhed for a bit, researched it, (even the cheaper versions) but i decided because my headaches were getting me down so much that i would plunge for the REAL thing, not cheap knock offs, and i am so glad i did! This brilliant device is keeping my sinuses clear and my headaches have gone! I am more than happy that i bought the real thing, i personally do not think that it is expensive for what it does! My ENT prescriptions were £20 - £30 per visit, and now i have no more prescription bills as this NovaFlow device has sorted my problem! I am mire than happy to use this brilliant device twice a day for the rest of my life! You HAVE to try it, be true to yourself and use it at least twice daily, (not just when you feel like it, something we are all guilty of) and hopefully like me, you will get the relief it is made for. I did have a little problem with mine and i contacted Cleriva and they got back to me within the hour with a solution that i am more than happy with! They care! So this is a reputable company. Which are hard to find these days, real people at the other end of the email, no automated response, just 100% help. Honestly i cannot recommend this device and company enough.
I am so thankful for the Cleriva !! I have always struggled with allergies and sinus infections. I use my Cleriva every day in the evening. I sleep better . I have not had to take any sinus medication or nasal sprays !! The red light is amazing!! The company is very helpful too !!
So far I love this device, it works really well and when I had a slight issue with one of the pegs being faulty, Coney from customer sevice was able to help me in a very timely manner. Would suggest to anyone suffering from inflammation
I was having great sucess using the device. THEN, I had it on the kitchen counter and it was accidently dumped into the sink full of water unknowningly. Well it no longer worked. I contacted customer service, CONEY helped me out and they are replacing it for me no charge!! So appreciate it. Since I have not been using the device my congestion and nasal soreness has returned Allergies

Maddy was very responsive and offered a reasonable solution to my defective unit. I have enjoyed my Novaflow so far and would like to continue to see the benefits.
Maddy immediately responded to my request for assistance when I encountered a problem with charging. The speed of the response is greatly appreciated.
I can't say this product doesn't work at all because you can't do a controlled study on yourself. And of course there's always the placebo effect. Certainly it is not the panacea it's advertised to be. I still need to use most of my other meds. As for the device itself, it's clear that this is a rebranded piece of Chinese junk. The product is shipped directly from China with no usage instructions whatsoever for anything included in the box other than meaningless statements converted from Chinese to English. It comes with a bunch of pieces that you'll simply have to figure out yourself what to do with. No American manufacturer gave any thought to how this was packaged or how you might even think to use all the parts. The power plug is an ancient USB-B which does nothing to reduce weight or power requirements compared to USB-C, it's just an old interface. It's indicative of the Chinese manufacturing era it comes from, and the fact that this device is simply rebranded. If you want to try red light therapy you can buy an identical device (without the branding) on Amazon for $15 instead of paying $50. And if you test the light frequency with a simply meter you'll find that they are all tuned to the "special" red 660nm frequency. You may or may not experience any small benefit, but don't waste your money on something with special branding that advertises all over social media.
Hi Jay, thanks for your honest review and we’re sorry the product didn’t work for you. Red light therapy isn’t a guaranteed solution for everyone, and we try to be transparent about that. NovaFlow is a wellness device, not a medical device or cure, which is why we don’t provide clinical instructions beyond standard usage guidance. We also want to clarify a few points about the product itself. While there are many similar-looking red light devices online, they are not the same NovaFlow devices. We have our own manufacturing team that quality inspects each batch before fulfillment. With lower-cost alternatives, wavelength consistency and build quality can vary significantly from unit to unit. And unlike the cheaper alternatives, we stand behind our products with a 120-day return policy because we understand it may not be the right fit for everyone. As for the USB connection, we chose that design intentionally to keep the device lightweight, comfortable, and easy to wear during sessions. Moving to USB-C would have required a larger internal battery and heavier hardware, which would make it a lot more uncomfortable. We genuinely appreciate the feedback and are always working to improve both the product and the customer experience. If you haven't already, reach out to our support team at [email protected] and we'll set you up with your free refund!
Coney responded right away when I needed. Thank you! If you haven't tried this, it works!
Customer service responded quickly, I received my item soon after. Haven’t noticed an improvement yet but it’s only been a few days of using.
Hi Laura, I’m really sorry for the worry and frustration this has caused. I completely understand why you’d feel concerned when the tracking hasn’t updated for several days. Please send us an email at [email protected] with your order number (usually a 5-digit number like #00000), and I’ll personally look into the shipment status for you right away. I’ll do my best to check what’s causing the delay and help get you a clear update as soon as possible. We truly appreciate your patience, and I sincerely apologize again for the inconvenience. We’ll make sure this is properly looked into for you.
I had an issue with the delivery of my product. I emailed customer support and they responded quicker than I expected, Maddy dealt with my issue promptly and got it resolved ASAP! Great customer service thank you
Coney was very knowledgeable and helpful in solving my issue as well as troubleshooting the problem I was experiencing. Would highly recommend this company.
Unfortunately, my original order appeared to have been lost by USPS. I contacted customer service, and they were extremely helpful. Maddy, in customer service, got right on the problem and looked into the tracking. Since it appeared that the items were lost in transit they offered me the options of a full refund or a complimentary replacement for the items I ordered. I chose the complimentary replacement, since I am really excited to try their product. Thanks to everyone who helped me, and a special thank you to Maddy and Coney!
Coney was so helpful and kind. Such excellent customer service. Thank you
Initial shipping was quick and great customer service. Dog ate my device and the Cleriva rep Coney shipped me out a replacement no questions asked! Worth a go. Combining Novaflow with antihistamines and a corticosteroid nose spray has got things under control for me.
I was skeptical of trying yet another solution for nasal congestion, sinus pain, and my springtime allergies. The last several years it seemed an inevitable cycle I couldn't break of sinus congestion that eventually led to needing antibiotics for secondary infections in both my sinuses and ears. My chiropractor has a fancy (and expensive) cold laser unit in the office and I had a good experience getting a sinus infection treated there, but getting appointments and driving to the office were not what I wanted to do all season long once the pollen started. So I responded to the Clariva ad. I liked that the frequency was precise because I knew from my chiropractor experience that the precision matters. Clariva is easy to use and definitely seemed to help. I added on the device that shines into the ear canal and that ended up being my favorite. It helped that horrid itchy ear feeling that nothing else had! I'm glad I tried it. --Ellen
I was impressed with the prompt responses when I first purchased my Cleriva red light nose device. I was informed about the shipment progress and recieved my device quickly. I have used it for about 2 months and I saw improvement in the first week of use. I experienced significant decrease of mucus buildup. And most importantly it has reduced the frequency of nose bleeds which had been very severe. Currently I have had only very minor nose bleeds and much less frequently. My latest request for help with a battery problem was attended by Corey with an immediate response to my email and a replacement unit at no charge. I am impressed and reccommend this device without reservation!
I purchased the unit but unfortunately it wasn't what I expected so Maddy was extremely helpful in refunding me. Thanks Maddy 🙂
Worked an absolute treat for over a year now, Need to keep up consistency with it to have great results. My Nova Flow did have an issue after a year but Spoke to the customer service team and Maddy sorted out a replacement right away!
