I second a Levoit. I have 3 different models right now in my house. They’re decent price and they last for years if you replace the filters on schedule. And I run my a few hours a day, sometimes all day. I have the core 300S and the 300S-P with WiFi in my living room and primary bedroom. I have LV-H128 in my kitchen. I used to have the LV-PUR131S but it finally died after 5 years
Air purifiers work remarkably well. We have a cat and dog and I sometimes suffer a bit with cat hair giving me a persistent sickly cough. I bought a small Levoit air purifier for the bedroom and was amazed at how much better I slept at night. I ended up buying a larger whole house air purifier, (same brand). On a normal setting they run silently and barely use any energy. Not sure about other brands but the Levoit purifiers have reusable filters which you just take out and vacuum clean every week or so. I'd buy one if the single room air purifiers and see if it makes a difference. As far as visiting other people's homes, there's not much you can do about it.
4 ways that don’t include fighting your pet into a bath or shower: Regularly clean out their ears! You can get pet-specific wipes for this so they don’t bother their ears, or solutions to put on cotton pads, but people often don’t realise how much smell builds up in dogs’ ears. It’s even worse as they age. Their ears are naturally producing wax and oils, and then they go exploring and rub their ears on everything which picks it all up, then they lay down in your floors and furniture with their greasy ears. Not to mention ear mites are a common occurrence also. People often assume smells must be coming from butt or mouth but the ears can get really pungent. Clean their bedding regularly and put easy to wash blankets over furniture they get on (you can choose nice looking ones, but the lighter and easier to wash the better), and wash those regularly too. Using biological washing detergent that isn’t heavily perfumed (they won’t go back on it if it’s too perfumed). And an air purifier. We have an automatic one and it’s amazing how it kicks into overdrive when a pet walks by with pollen, dust and dander on their coat. It’s the levoit brand. You can also get dry shampoos for dogs and cats which go into your hand or a glove like a foam but dry into the coat as you rub it in (no need to wet them first). It’s designed to break down the bacteria that leads to smells and reduce the frequency of baths. I recommend gloves because some oils and grime can be released from the coat when you are rubbing it in. You can even get rubber or silicone gloves with nodules on them to massage it deep into the coat.
Mine catches me every time my cooking is burning in the kitchen. So I kinda know it works. Cooking smoke (oil droplets) should be in the PM2.5 category, which is what you should worry the most. Mine is Levoit Smart Air Purifier. And yes, they do shred microplastic themselves.
Hey! I have 5 Levoit smart purifiers around my home on Google Home ecosystem, and it works flawlessly.
I bought a Levoit smart air purifier. I just turn it on with the button. Never used the app.
