Oh shit.

#Hantavirus spreads like any other virus. You DO NOT need prolonged periods of time or close contact.

Don't listen to anything you hear from the current administration. This could be a big deal.

Here we go again.

But don't panic. Stay alert.

Heat Recovery Ventilator (HRV) — Operating Principle

A recuperator (heat recovery unit) transfers heat from exhaust air to incoming fresh air without mixing the two streams.

---

How It Works

Two airflows:

Exhaust air (warm, from indoors)

Supply air (cold, from outside)

They pass through a heat exchanger:

separated by plates or channels

no direct mixing

heat transfers through the material (conduction)

Result: → supply air is preheated
→ exhaust air is cooled
→ overall heat loss is reduced

---

Types of Recuperators

1. Plate Heat Exchanger

aluminum or plastic plates

efficiency: ~60–90%

no moving parts

2. Rotary (Wheel) Heat Exchanger

rotating drum

transfers heat and some moisture

efficiency: up to ~85–90%

3. Counterflow Heat Exchanger

air streams move in opposite directions

highest efficiency: up to ~95%

---

What Is Transferred

heat (primary)

sometimes moisture (in enthalpy units)

---

Efficiency Example

outside: 0°C

indoor: +22°C

after recovery: ~16–20°C

---

Advantages

reduced heating energy demand

continuous ventilation without major heat loss

improved indoor air quality

---

Limitations

frost formation in winter (needs bypass or preheater)

filter maintenance required

upfront cost

---

Core Idea

A recuperator doesn’t generate heat — it recovers and reuses it.

Here is why you should open your #windows whenever you can. On the left, is 2:05 PM when I’ve had the windows closed all day, the #CO2 levels in the house are high, indicating poor #ventilation. Now swipe to the right image, the levels have dropped to a third after leaving the windows open for over 2 hours, indicating excellent ventilation. High CO2 levels indoors can cause various #health issues including #tiredness, #headaches, #eye #irritation, #dizziness and/or #difficulty #concentrating, so please check your levels inside your house. I borrowed this CO2 monitor as well as an #AQI monitor from my local #library

Should We All Be ‘#HouseBurping’?

The German practice of “#lüften” is gaining traction on social media. It may improve your home #AirQuality.

By Dorie Chevlen, Jan. 29, 2026

Excerpt: "Experts say lüften actually works. The Environmental Protection Agency recommends opening windows to reduce the concentration of volatile organic compounds [#VOCs] in the home, which are released by a vast array of household items, including furniture, mattresses, cosmetics and cleaning products. These compounds can cause adverse reactions like headaches, itchy eyes and breathing problems.

"According to Dr. Parham Azimi, research associate at the Harvard T.H. Chan School of Public Health, there’s also reason to believe airing out a home regularly could help control household #mold. In his research, keeping windows closed correlated with a higher likelihood of mold.

"Dr. Joshua Nosanchuk, a professor and microbiology researcher at Albert Einstein College of Medicine and an infectious disease physician at Montefiore Health System, said that better #ventilation could eliminate many airborne toxins that cause people irritation in the U.S. 'Part of the problem is that we hermetically seal our houses. We don’t want the air conditioning to get out and we don’t want the heat to get it out,' he said. 'No one opens their windows.' "

I had lunch today at a tiny restaurant which was crowded the whole time I was there. CO2 never got above 700, and most of the time it stayed below 600.
I can't imagine that's coincidence. The owner of that restaurant must have put conscious effort into ensuring adequate ventilation.
We could do this everywhere. Indoor air quality could be good in every indoor space.
Instead, we're just letting people get sick over and over.

@harold Incisive thinking by two women to whom we owe much, 163 years apart! The paper by @trishgreenhalgh et al is of interest way beyond public health, illuminating blindspots & pyschological limitations which constrain our collective response to many new challenges. It’s so well written it’s a joy to read, & to re-read… but also very disconcerting.
