Hi, modular cages, double critter nation cages or xxl dog crates are all cages we usually recommend. Here's a few links of modular cages and other:- https://www.amazon.com/Indoor-Playpen-Outdoor-Detachable-Exercise/dp/B0FR4RMM9X- https://www.amazon.com/VISCOO-Enclosures-Playpen-Detachable-Exercise/dp/B0FD3BG6P5- https://www.amazon.com/MidWest-Critter-162-leak-Proof-Measures/dp/B001NJ0DAY (More expensive but I'm pretty sure that's the double critter nation cage people like) No matter the cage always make sure the gap between the cage bars is small (0.5 - 1 inch) Also here's an estimate of the numbers of modular cage's panels you need to make those cage size:- 3 rows lenght, 2 rows height, 2 rows depth: 107x70x70cm | 42x28x28 inches = 32 panels- 4 rows lenght, 2 rows height, 2 rows depth: 140x70x70cm | 55x28x28 inches = 40 panels- 4 rows length, 3 rows height, 2 rows depth: 140x107x70cm | 55x42x28 inches = 48 panels- 4 rows length, 4 rows height, 2 rows depth: 140x140x70cm | 55x55x28 inches = 64 panels (what I have, you will need to buy at least two large cattios to make this so more expensive)

Glad it helps! It's a filter type, not brand. I send a full list of links to someone recently, I'll paste here at the end or in a separate answer. Basically it needs to be an air purifier with a TRUE HEPA filter, non ionizing. Some air purifier have essential oil (aromatherapy) feature, just never use it. I do a big mix, the brands I use is Versele Laga but it's not the easiest to find in the US. You want something that has a good variety of seeds (at leats 6), not a majority of one seed (usually millet, loved by birds, not good health wise in so much quantity) and with no additives or weird stuff, honey or things to "make them eat". No corn, or just pop corn, super fat. Personnally, I pick several seed mixes, and then add in it lentils, and rice, and other seeds. Any kind, food grade, no added salt. If you add one type of lentils + one type of rice in your mix you'll have a good variety There's a lot on amazon, the wood platforms are great on amazon but I strongly suggests making diy wood perches for your money. You can buy this set of screws, go outside and pick a safe wood type (no pine trees, personnally I have uh... Nut tree lol, dont know the english name) The screws:https://www.amazon.com/Platform-Accessories-Suitable-Playgrounds-Breeding/dp/B0DCG1Y93J Example of good platform: https://www.amazon.com/Accessories-Grinding-Standing-Climbing-Lovebirds/dp/B09TDRRDJN Big unexpensive cages are called cattios, I got several from the brand YITAHOME. Some people takes large dog crates too. I still prefer the cattios, because they're modular cages so if you ever need to give them more space (like if you move out) you can just buy an extension and add it to the cage. Dog crates have big bar space gaps usually so I'm less fond of them, because it increases the risk of the birds stucking their heads in. Cattios example: https://www.amazon.com/dp/B0FD3BG6P5 Note that cattios have shitty floors though (usually the black panels), what I did is bought an extension, put a grid for floor AND placed a custom cut gym mat inside (birds should never be let walking on grids they can get hurt). You didn't ask but I just thought about it, for flooring there are several options. Newspappers, liners, potty pads... Personnally, I didn't like throwing away stuff every so often especially since mine are in big cages, so I ended up buying an anti slip transparent mat (the kinds you put below gaming chairs so it doesn't scrape the floor) and cut it so it fits the full cage, it sure was expensive but it's reusable and so far it holds on like a charm. I scrape the poops off with a freezer scrapper, and clean it with a sponge with white vinegar, for deeper cleans.
