САМЫЕ вредные ЭТАЖИ для ВАШЕГО здоровья! НИКОГДА не покупайте квартиру на ЭТИХ этажах.

Key wellness & self-care takeaways (health-focused floor selection)

Avoid the lowest floors (1st–2nd) for respiratory comfort

• More street dust, exhaust, and odors from below.
• Greater likelihood of noise and exposure to commercial activity (shops, restaurants, pharmacy) at street level.
• Potential for rodent issues.
• Lower-floor residents are described as being more prone to weakened immunity and respiratory infections (e.g., allergies/rhinitis/asthma).

Be cautious with extremely high floors (25th and above) for cardiovascular concerns

• Atmospheric pressure changes are described as a factor linked to headaches and anxiety.
• Elevator-related stress, dry air from HVAC, and limited window ventilation are noted.
• Infrasound/vibration from building sway is mentioned as potentially contributing to anxiety, insomnia, and headaches.

Productivity / decision-making strategy (how to choose confidently)

Don’t rely on old myths

• Don’t assume sayings like “4th–7th is best” or “above is always bad” are universally true.

Use a facts-based shortlist

• Worst: 1st–2nd and 25th+
  • (for different reasons)
• Best “well-being + practicality” zone: 4th–12th
• View-focused middle/high: 14th–20th (only if the view won’t be blocked)

Choose based on surroundings, not just the floor number

• Check the master plan before buying to see what will be built across the street (the “view trap”).
• Verify construction risk near the building—resale value can drop sharply if the view disappears.

“Golden mean” floor guidance (what to pick and why)

Recommended for living, health, and resale demand: 4th–12th

Not because “heavy metals settle lower” (the video frames that as outdated), but because these floors are described as:

• high enough to reduce direct street annoyance/dust impact,
• low enough that you’re less dependent on elevators (e.g., during breakdowns).

The video also claims these floors have stronger resale liquidity (they sell faster).

Premium views: 14th–20th

Works best when the building orientation ensures light/air/panorama won’t be blocked.

Avoid

• 1st–2nd for lifestyle quality,
• 25th+ for certain health concerns.

Premium-building note (why 1st/last can be expensive—and sometimes better)

In elite/premium buildings, the video argues the old “first floor is terrible” idea doesn’t always apply because:

• the ground floor may be fully residential (not commercially used),
• there’s no commercial space under windows,
• there may be courtyard/closed territory (less noise),
• ventilation/air filtration and professional management may be improved.

In the same category, top floors (penthouse) can be expensive due to views, private elevator access, and higher ceilings.

Investor-style framing (resale strategy)

• The speaker suggests floor choice can impact resale by roughly 10–15% (either a higher price or an equivalent discount).
• Upper view floors may be better for investment only if the view is protected by the master plan and won’t be blocked.
