A neighbor purchased his Vietnamese MIL a propane grill with a stove top.

Most days, around 11:00, I could smell her cooking, might have been mackerel.

Either a strong stove hood or outside.

I'm thinking about purchasing LEVOIT Air Purifier with H13 True HEPA Air Purifiers Filter for Home Allergies and Pets, Smokers, Smoke, Dust, Mold, and Pollen, Air Cleaner for Bedroom, Large Room with Optional Night Light, LV-H132

we cannot afford a hood, and we try to open the windows .. but we live close to the road so it is dusty...@User

There are scent-free odor neutralizers, sprays. I’ve seen Odor Bully at Bed Bath & Beyond and certainly there are others available elsewhere. But please understand that odors will also cling to drapes and carpets so it may be difficult to completely eliminate odors.

Do you have a garage or carport which could be used for cooking? How about close all household doors blocking rooms off from kitchen? Cook on the side of the house away from the street?

thank you

check out odor eater candles, they work great
