> although probably not more effective than a saline solution

I guess saline is a baseline against which effectiveness should be measured here, especially since nasal sprays are usually saline plus something. (I guess? Not sure about Sudafed specifically.)

I'd argue that saline should be the panacea here. I doubt very many people do at-home saline rinses with filtered, sterilized water and a simple mixture of salt and baking soda.

Do people really want to spray PFAS water directly into their mucus lining?

I bought an Arm and Hammer Saline spray out of curiosity. It smelled awful, and the BPS lined can had an awful smell despite the ingredients being: water, salt, baking soda, and no suspicious preservatives.

True except it is definitely more effective than saline. Phenylephrine nasal spray is not as effective or long-lasting as oxymetazoline, but it's also not as dependency-inducing.

The efficacy of the nasal sprays had already been demonstrated when they introduced the pills. Surprisingly, the efficacy of the pills was never properly demonstrated, and now that it's being investigated, they're pulling it from the shelves.
