Bringing home a new cat is exciting. But in all the preparation — litter box, food, toys, scratching post — there's one thing most first-time cat owners forget: the air.
This checklist is designed for the first week with your new cat. Not the science of why air quality matters (we've covered that elsewhere), but the actual actions you need to take. Print it, save it, check it off — and give your new cat the cleanest possible start.
Before Day 1: The Pre-Arrival Setup
These are the tasks you should complete before your cat comes home.
- Choose the main cat room. Pick a room where your cat will spend most of their time initially — a quiet space with a door you can close.
- Vacuum the room thoroughly. Carpets, furniture, baseboards — everywhere your cat will have access.
- Wash all bedding and textiles in the room. Hot water (130°F / 54°C) breaks down existing allergens.
- Damp-wipe all surfaces. Tables, shelves, windowsills — use a damp microfiber cloth, not a dry duster.
- Place an air purifier in the room. Set it up near where your cat's bed will be. Run it on medium speed for 24 hours before your cat arrives.
- Change your HVAC filter. If you haven't done it recently, now is the time.
- Open windows for ventilation. If weather permits, air out the room for a few hours before your cat comes home.
Day 1: Arrival Day
Your cat is home. Here's what to do with the air quality setup today.
- Keep the cat room door closed. This creates a controlled environment and prevents your cat from feeling overwhelmed by the whole house at once.
- Run the air purifier on medium. The W-Cat's 360° intake captures allergens from all directions while your cat explores.
- Don't open windows. Your cat may try to escape through an open window. Keep them closed today.
- Watch for respiratory signs. Some sneezing is normal (new environment), but heavy breathing or wheezing is a concern.
- Keep the litter box clean. Ammonia builds up fast — scoop after each use today.
Day 2-3: Settling In
Your cat is starting to adjust. Now it's time to start the routine.
- Run the air purifier 24/7 on low. Continuous operation maintains a stable clean-air baseline.
- Vacuum the room again. First-day shedding is real — get that fur out of the carpet.
- Wipe down surfaces again. Dust and dander accumulate quickly in the first few days.
- Check the air purifier's pre-filter. If you see visible fur accumulation, replace the pre-filter (it's disposable).
- Wash your hands after petting. This is a new cat, and your immune system is adjusting too.
Day 4-5: Expanding the Territory
Your cat is ready to explore more of the house. Here's how to manage air quality across more space.
- Open the cat room door. Let your cat explore adjacent rooms at their own pace.
- Place a second air purifier (if available). If you have a second unit, put it in the next room your cat starts using.
- Vacuum the expanded area. Any room your cat has access to should be cleaned first.
- Check for new hiding spots. Cats hide where allergens accumulate — under beds, behind furniture. Wipe down these areas.
- Monitor the AQI indicator. The W-Cat's AQI light shows you air quality changes as your cat moves to new areas.
Day 6-7: The New Normal
By the end of the first week, your cat should be mostly settled. Here's how to lock in the air quality routine.
- Establish the 24/7 purifier routine. Run the W-Cat continuously on low speed in the room where your cat spends the most time.
- Set up the weekly cleaning schedule. Vacuum at least once a week, wash bedding weekly, wipe down surfaces weekly.
- Check and replace the pre-filter. After a week with a new cat, your pre-filter has caught the initial burst of dander and fur.
- Order replacement pre-filters. You'll need them. The W-Cat pre-filters come in a 10-pack — reorder when you're down to 2-3.
- Assess whether you need a second purifier. If your home is larger than one room + bedroom, consider a second unit.

Why This Checklist Works
The first week with a new cat sets the pattern for everything that follows. If you establish good air quality habits from Day 1, you'll prevent allergen accumulation rather than trying to correct it later.
This is the same principle that applies to litter boxes: you wouldn't wait until the smell is bad to set one up. Air quality works the same way. Prevention is easier than correction.
💡 Pro tip: The W-Cat's real-time AQI sensor shows you whether your air quality is improving over the first week. Watch the indicator light transition from yellow/orange to green — that's your sign that the purifier is working.
How the W-Cat Helps in the First Week
The W-Cat is designed specifically for this scenario — bringing a new cat into a home where air quality matters.
- 360° air intake captures allergens from every direction, regardless of where your cat is exploring
- 3-in-1 filtration (pre-filter + H13 HEPA + activated carbon) handles dander, fur, and odors
- 8 manual speeds — medium during the day, low at night, high when you need to clear the air quickly
- Real-time AQI sensor shows you air quality changes as your cat moves through different rooms
- Whisper-quiet 23 dB — won't startle a nervous new cat
