Hi everyone,
I'm looking to buy an air purifier for my home but I'm not sure which features to prioritize. I've seen so many options online, and it's a bit overwhelming. Can anyone recommend a reliable brand or model that’s good for dust and allergens? I’d really appreciate some guidance!

Thanks in advance!

The best air purifiers have HEPA filters. Standard air purifiers don't really filter out all the pollens and the dust mites in the air, so HEPA filters are what we usually recommend for indoor allergens. Air purifiers are listed according to the square footage, so make sure you buy one that's appropriate for the size of your room.

When you're looking for an air purifier to buy, the main feature to look for is how well it can filter out dust and allergens on the lower settings and how quietly it runs.

If you're trying to purify the air in a small room, the GermGuardian AC5350B is a great choice for a bedroom, office, or other smaller spaces.

For medium and large rooms, we recommend the BlueAir Classic or Coway AirMega because they have more powerful filters and make the least amount of noise, even when they're on higher levels.

How to check for potential bed bug infestation in my house?
I truly, deeply hate to say it...but I'm afriad that I have bed bugs. I haven't found a beg bug YET, but I've been waking up itchy all week. I'm concerned there could be an infestation because I've heard if there's one there's usually many. How do I check for bed bugs? More importantly, what do I do?? Thank you so much!

How do I get rid of these silverfish? So gross
Ugh ugh ugh, I just moved into an older building recently and noticed a lot of those gross silverfish bugs crawling all over the place. Like, I know they're not going to hurt me or do anything, but I'm still getting an icky feeling knowing that they're in my home. I just want them gone as fast as possible so I don't have to deal with them anymore. Any tips to make my place silverfish-free for good?

Need Help Maximizing Space in a Small Apartment
Hi everyone! I recently moved into a small apartment around 500 sq. ft, and I'm struggling to make the space feel open and functional. Does anyone have recommendations for furniture, storage solutions, or design tricks that make small spaces look bigger? I'd love to see examples or hear about your experiences!

I tried rearranging my living room furniture to create a more open and inviting space. I expected the room to feel more spacious and well-organized, but instead, it still feels a bit cramped. I was hoping for a better flow and a visually balanced design, but something seems off. Any suggestions on how to improve the layout or choose better furniture arrangements?

How do I get rid of fleas for good?
I'm mortified to be here asking this but I'm desperate at this point: I have fleas in my house and I dont' know how to get rid of them. They seem to really like my dog (mostly indoor dog but we use flea and tick meds) and the couch. I wouldn't say it's an infestation just yet, but it's been like this for months and nothing I do is keeping them away! What should I do/what am I doing wrong?
