I was sceptical that this would work for long term sinus issues including a post nasal drip but this has helped me tremendously. I use it every day, up to 3 times if feel slightly blocked up and have not been having the same sinus headaches or nasal congestion or discharge as before starting to use it a couple of months ago. It did take a couple weeks to be delivered but it was worth the wait.

replacement I ordered a Nova Flow in May. in Sept my puppy chewed it and destroyed the plastic posts that the cushions fit on. I asked if it were possible to replace the posts and the customer service rep offered to send me a new unit. I really appreciate this as I am exhausted from replacing things the puppy destroys and it was nice to get some actual support.

Although the device, for me, was pretty slow to start making a difference (i was cloged for years) when it finaly kiked in it did a great job, i can now breath all night from my nose and i sleep better. In order to have good results i had to jump from 10 minutes 3 times a day to 20 minutes 3 times a day to realy make a difference. The device is reliable until it quits (i have had 2 that just stop working after many months but the service is very good to replace the last unit ( the first one i just trash). I would appreciate more details on the utilisation like how long is it safe to use, do you stop when you fell better,etc. I highly recomand this product, maybe a more solid version for long time users

The item did not work for me, but the customer service was excellent. I was given a full refund with no quibbling. Coney Angel Arcilla was an absolute star!!

I was sceptical about this product, but nothing else was helping with my sinus problem. It was delivered quickly and I tried it. For the first time in years I could breathe freely. No coughing in the morning, no more mouth breathing. Which btw my mother always told me off for! I now use it every two or three days to keep my sinuses clear. Best thing ever and saving me a fortune on antihistamines and nasal spray.

Ms. Coney Angel Arcilla was very kind and understanding of my issue. And also my technology shortcomings, She is an excellent support manager for your company. You are very fortunate to have her working for your company. Very fortunate. Please continue to promote her within your company, Thank you. Charlie Schnell 11/13/25

Amazing customer service department product delayed but they kept me updated

Ordered nearly 2 weeks ago and it never arrived. Buyer beware!!! First and last time I’m ordering something from a Facebook ad 😡 **EDIT 16 November** I am now changing my review from 1 to 3 stars after customer service got in touch with me. It looks like my package took a very long time to clear UK customs, and once it was cleared it was subsequently lost in the post. The customer service representative has been very communicative with me and I’ve now received a full refund. I’m glad that it’s been resolved, but I can’t give a higher review than this because I never received the product. I understand that it was not the fault of Cleriva that my package was lost. However, I would not have ordered from them if I’d known that they were based overseas. The website gives an American mailing address but I believe the product is shipped from China.
