Luggables

Yeah, as long as you don't mind some easy assembly (they typically take me 30 minutes), the ones that use computer fans and MERV 13 furnace filters are the best performing - they are quiet, have a high clean air delivery rate, and have a large air envelope. Having a big air envelope means they move more air around, and so particulates in the air get removed more quickly, since the air is moving around more. I have a bunch of the [CleanAirKits Luggables](https://www.cleanairkits.com/products/luggables), they are great. There is also the [Nukit Tempest](https://cybernightmarket.com/products/the-nukit-tempest-pro-complete-air-purifier-kit-usa), although the tariffs have made it more expensive. 2000 square feet is a LOT. With four of the XL Ultra Luggables, you'd have 1333 cfm of smoke CADR, which is the recommended amount according to AHAM. That said, you could start with one or two of them, and see whether that's enough for your space. More units also helps since the reach of any single unit is limited. These type of air cleaners are by far cheaper to run than HEPA-based cleaners. You have to take into account the cost of replacement filters and the electricity cost. HEPA cleaners use a lot more electricity.

I have the luggable with some different pc fans as I bought the fanless kit. Works great with the Costco 3m merv 14 filters which are on a great sale atm.

Costco sells the c909 online I’m not really a fan of the 610 tbh as there’s no separate pre filter I have one of the xl luggables from clean air and it’s pretty great for air flow to noise. I bought the fanless kit and use 3m merv 14 filters from Costco in it.that may be pushing your budget tho as there’s fanless kit is like 150 even with a 5% discount code. And then you need filters and fans. even with buying something like two artic p12 pro 2000rpm low noise 5 pack and say Costco 3m filters for 35. That would put you at like 250+ cost.

Clean Air Kits Luggbales Like a CR box but very quiet. Low energy usage. Takes regular MERV-13 filters you can buy anywhere [https://www.cleanairkits.com/products/luggables](https://www.cleanairkits.com/products/luggables)

I got the Luggables XL-7 for 300$. It was the best PC purifier I could find.

Clean Air Kits Luggable 7-fan purifier. You have to assemble them yourself, but I did 5 of them by myself and I am NOT handy at all, so it's totally doable. I bought several of these for my home and my kids' activities. They're pricey, and you have to stay on top of when to change out the filters (which means essentially disassembling them), but they are great. Very silent and totally worth it, IMO. Good luck! It sucks to be backed into these decisions when our babies aren't old enough to mask or advocate for themselves. :( I'm sorry you're in this position, and I am sending you lots of positive energy.
