At 30cm distance, facing the middle of 4Lite: 0 μg/m3
When positioned above or below the middle: 1 μg/m3
When shifted left or right: 2–6 μg/m3
This proves that correct positioning significantly improves performance—so always aim the center of 4Lite toward your face for the best results.
(2/2)

Once you receive your PCR test report, the same app allows you to purchase appropriate medications for treatment.
I consider it very convenient. Whenever my family member is not feel well, I will arrange a PCR test for them.
Specially I can avoid taking kids to the hospital, where is quite risky.

🔻Extended Panel (RMB 159 / ~$22 USD) – Includes all pathogens from the Basic Panel, plus:
🔹Group A Streptococcus
🔹Bordetella pertussis (whooping cough)
This option also provides pathogen load (viral/bacterial concentration) in addition to positive/negative results.

After collecting the samples, you place both swabs back into the provided test tube and return it to the worker. They will then deliver it to a lab for analysis. Typically, results are available on the app within three hours.
There are two testing options for respiratory pathogens:

Within two hours, a healthcare worker will arrive at your specified address with a sampling kit, which includes:
🔻A long swab for throat sampling
🔻A short swab for nasal sampling
🔻A test tube to keep the samples

I just saw the video. The key problem is how to direct the clean air to the nose.

Yes, we are going to produce them very soon.

There needs to be some room on its intake, but not much. you can put it on your knees with room in between.

Focus on educating people about lung tumors which you know and stop commenting on masks which you don't know."
Guess what? He deleted the video within a few hours.
A well-known doctor spreading disinformation can have a huge impact, and we need to stand up and call it out directly.

I left a comment saying:
"Please stop spreading nonsense. You’re an expert in lung tumors, but masks are in a completely different field, and it’s clear you haven’t studied them. I bet you don’t even know the national standards for masks or have ever read any of them.

Commercial companies often use this as a marketing gimmick, promoting H13 as the best without considering the impact on overall performance.(7/7)
comment in response to

I don’t believe H13 can provide the highest CADR in any case. H13 filters are ideal for devices like biosafety cabinets, where maximum single-filtration efficiency is required, but not for conventional air purifiers. (6/7)

I conducted a test on the 3Pro model, which achieved the highest CADR with E11 filters. While this may not apply to all air purifiers, for PC fan types, E11 filters are the most effective choice.(5/7)

We can't just say one filter level is better without considering these factors. The best filter level strikes a balance between filtration efficiency and the airflow rate drop due to the pressure drop from the filters. (4/7)
comment in response to
post
However, if you're making your own air purifier, filter choice becomes a key factor to achieve the highest CADR.
So, which filter is better? The answer depends on two main factors: the total surface area of the filters and the combined P-Q curve of the fans.(3/7)
comment in response to
post
Before diving deeper, it's important to understand that if the CADR (Clean Air Delivery Rate) is the same for both air purifiers, they essentially do the same job, regardless of the filter level. As a customer, this means you should focus on the CADR rather than the filter level. (2/7)

Thank you for your support.

Thank you. The corner will be rounded off.

Later, I will install fans and filters on it, and test it in the lab. Hopefully it can remain similar CADR as 3Pro.
Thank you for supporting AirFanta. Your support has been crucial in providing the funds needed for this iteration, and I truly appreciate it!

But they are different type of air purifier. Exhalaron aims to clean the whole room, and AirFanta 4Lite is a laminar air purifier. It aims to blow clean air to your face to breathe, instead of clean the whole room.

We have only 3Pro with HEPA filters and seperate carbon filters as replacement in AU.

If I were a consumer, I wouldn’t be happy to see the price of replacement filters increase, forcing me to either accept the price hike or go without. So, we’ve decided to absorb the cost ourselves and keep all prices the same, including the air purifers.
Let's clean the air. (2/2)

I am glad that it helps.

Currently, it's only available in the US. Sales in Canada, the UK, the EU, and Australia have been quite low, so additional inventory in those regions could result in unsold stock and high storage fees.

about 180USD without VAT.

You can order it on our website air-fanta.com.

There is only less than 10% people who mask. And 90% of the masking people are wearing surgery masks. Situation in Japan is better.

Yes. But replacement filters are only available on Amazon. Because they are in Germany warehouse and only via Amazon, they can be delivered.

Indeed. like 2 x Airfanta 3Pro at 7v.

Yes. The power adaptor works with 110-220v/ 50 or 60Hz. Only you need a travel adator to change the plug type.

Canada hasn't impose tariff on China. So the price will remain the same.
comment in response to

Taxing all the small packages will take a lot of work. USPS doesn't have the manpower to do it. I wonder whether the tariff charged can ever cover those work. The policy is not well-thought-out.

Yes, it use the same filter of the Mini. and better replace it every 3 month if you use it 1 hour every day.
