I work outside in arid SoCal. I don't have allergies, but am often on trails in clouds of dust. I usually have boogers, never saw it as a problem, I just blow my nose a lot to try to get them out. Santa Ana winds and wildfires always wreck my nose. Face masks help a bit. I though it just was the way it is. I got too close to a stinky car fire the other day, and within a few hours, I realized my nasopharynx and sinuses were adversely affected, irritated and swelling. It was late, and so the drug stores, big box stores, even grocery stores were all covid-closed, so I researched a few things online and though it seemed kinda pricey, I subsequently ordered the Navage. It arrived about an hour ago. I immediately opened the box, added distilled water, the pod, assumed position over sink, stuck it up my nostrils, pressed part way to feel suction and then all the way to let the water flow. It was not as powerful as I thought it would be, but I did it again and realized/learned to not push it into my nose so hard; it actually works best if I am maintaining seal while pulling back on the device as if to pull it out of my nostrils (but I don't). THAT improved the suction for me. There were a couple of moments water went toward my throat, but saying "ahh" while the machine is operating solves that. Immediate relief! I must say I feel like I've just discovered my nose. It's like I'd been only using one nostril all my life and now I have 2! I am so glad to have discovered this! Especially with all the trail dust everyday and the wildfire smoke I am currently exposed to. This may be pricey, but I am glad I got it.
